tips to identify bubble tips anemone

The bubble tip anemones are one of the most attractive anemone species. They have soft, polyp-like bodies. 

They are of ranges of colours. Most commonly bubble tip anemones are green and pink in colour. There are slender and flexible organs present near the mouth of the bubble tip anemones. They are called tentacles. 

Tentacles occur in one or more pairs. They are used for grasping and feeding purposes. There are bubbles like formations at the end of the tip of their tentacles. That is why these anemones are called bubble tip anemones.

They can grow in size up to 30 cm (12 inches) long.

Bubble tip anemones are native to Fiji, Singapore, Indonesia, Philippines, Tonga, and Vietnam 

different types of Bubble tip anemones

Green Bubble Tip Anemone

Green Bubble tip anemone

Green bubble tip anemones are a variety of bubble tip anemone. They got green coloured bubbles at the tip of their tentacles. 

They need strong illumination to keep bright colouration and bulb tips. If the lightning is not enough, they will expand their bodies to get the maximum amount of available sunlight.

As a result of receiving insufficient sunlight, their tentacles may appear like rings. This condition may also develop due to the lack of food. Therefore, enough food should be given to the green bubble tip anemones. 

Chopped fish, shrimp, or worms are the diet for them. Green Bubble Tip Anemone should be kept with clownfish. The reason for this is sea clownfish can help anemones to catch their prey.

Rose Bubble Tip Anemone

Rose Bubble tip anemone

The Rose Bubble Tip Anemones are a rare colour variety of the Bubble Tip Anemones. At the end of the tentacles, they have risen to red enlarged tips. This gives them a fantastic outlook to keep them in marine aquariums.

Rose Bubble Tip Anemones need a large and more spacious aquarium system. The reason is that they can be raised in a mixed range of coral types. 

The aquarium needs a strong filtration system to maintain high water quality conditions. The Rose Bubble Tip Anemones can grow up to 12 inches in diameter. 

Rainbow Bubble Tip Anemone

Rainbow Bubble tip anemone

The Rainbow Bubble Tip Anemones are fine colour combinations of orange and green bubble tip anemones. As same as other Bubble Tip Anemones, they make outstanding hosts for ClownFish. These anemones are roughly 3.5-4 inch in diameter.

Black Widow Bubble Tip Anemone 

Black widow Bubble tip anemone

Black Widow bubble tip anemones are also a type of bubble tip anemones. They are bold metallic in colour. Black Widow bubble tip anemones have bright webbing and deep red colour foot. Splashes of white snowflake-like patterns can be seen in the body.

When propagating Black Widow Bubble Tip Anemones maintain water parameters in good condition by regular or partial water changes. 

They like a good amount of water flow within the tank. This can be created using pumps and powerheads. These pumps need fairly low maintenance, and they can add a neat look to your tank.

Tank requirements for Bubble Tip anemone

BTA aquarium

The tank requires special criteria and conditions for the bubble tip anemone to survive. Water in the tank is a critical factor when raring bubble tip anemones. The reason is anemones love to enjoy the good conditions of the water. 

Size of the tank

The minimum tank size suitable to propagate Bubble tip anemone is a 30-gallon tank. The tank size depends on the type of Bubble tip anemone that is going to propagate.

Under ideal conditions, Bubble tip anemones can grow up to 12 inches in diameter.

required Water quality 

Salinity level

High water quality conditions should prevail inside the tank. When you measure the salinity using a Hydrometer, measurement comes as a specific gravity. salinity of the water should be between 1.023 – 1.025 (specific gravity).

Water temperature

Temperature should be between 25°C – 28°C (77° F -82.4 °F). You can install an aquarium heater to maintain temperature at a stable level.

pH of the water

The pH of the water should be between 8.1 and 8.4. Use a digital pH meter to measure the pH.

Water Hardness

Alkalinity should be maintained between 8-12 (mg/L).

There should not be dissolved ammonia and nitrite in tank water. You should maintain low amounts of iodine, phosphate, and nitrate in tank water.

These conditions encourage the healthy growth of the blue tip anemones. Maintain water parameters into favourable levels by regular, partial water exchange. 

Bubble tip anemones like a good amount of water flow within the tank created with pumps and powerheads.

Flow rate of the water

Regular and partial water changes will help to maintain water parameters in good conditions. Bubble tip anemones prefer a good amount of water flow within the tank. This can be created by using pumps and powerheads.

Lighting in the tank

Bubble tip anemones need plenty of light. It helps them to get the energy to make their food. Foods promote the growth of the anemones. In another way, light improves their skin colourations. 

Therefore, light requirements should be a high priority in this regard. Bubble tip anemones need moderate to high light intensity to grow well. 

The tank will therefore need bulbs, Metal halides, T5 fluorescent bulbs, 14-20K colour spectrum to produce the necessary amount of light.

How to place a bubble tip anemone in a tank

BTA aquarium

Bubble tip anemones are quite mobile. They move towards the direction of lightning and water flow in your tank. Therefore, do not expect them to stay still in the tank. They will attach to any glass, rock, or solid surface in the tank. 

  • Be mindful to protect pump intakes and overflows from bubble tip anemones in case of getting sucked up. 
  • Be mindful to maintain a good flow of water inside the tank. When placing bubble tip anemones inside the tank, the flow should be turned down. Water flow can be increased after attaching anemones to a rock.
  • Maintain a space of 3 or 5cm in between the anemone and the corals.
  • When the bubble tip anemone attaches to an unwanted place, direct a water flow towards the anemone. Then it may reattach somewhere suitable.
  • Remember to minimize the handling of bubble tip anemone as much as possible.  
  • A healthy anemone tank placement is mostly dependent on more knowledge of the aquarist. 
  • Get a bubble tip anemone care guide to learn more about the procedure of healthy placement of an anemone.

How to frag / propagate them

BTA propergate

Bubble tip Anemones are amazing creatures when it comes to reproduction. Depending on the exact species, they can reproduce either sexually or asexually. Asexual reproduction methods use to propagate Bubble tip anemones are budding, fragmentation and fission.

Farmers identify “fragmentation” more commonly as “splitting “. This is the most popular method of propagating Bubble tip anemones in captivity.   Propagating Bubble Tip Anemones is easy. Simply cut them equally into two halves. 

The most challenging step is husbandry and raising them to a healthy size. When they grow up, cut again and continue the propagating cycle.

  • Cutting bubble tip anemones with a razor blade or scalpel is less stressful than the natural binary fission process that occurs in the ocean.
  • Use large hydroponic trays to propagate the Bubble tip anemones.  
  • The shallow trays are ideal for this purpose. The reason is that these trays have a large available surface area and minimal water volume. 
  • The smooth surfaces allow you to remove the Bubble Tips easily that are attached to the tray.
  • Filling the tray with recommended biological filter media. It provides Biological filtration and a substrate for the anemones to attach to.
  • Rubble rock or crushed coral can also be used as substrates.

How fast do bubble tips anemone grow?

The growth of the Bubble tip anemones is dependent on several factors. They include mainly how much you feed it, light availability and the water quality conditions of the tank. If these factors are at favorable levels a sudden growth can be achieved. 

Normally, 4 inches of growth rate can be achieved in Bubble tip anemones within 2 months. But all the factors should be kept within favorable levels. Simplify if you did not feed them properly anemones would not be grown as fast.

What do bubble tips anemone eat?

BTA eat

How to feed

Bubble tip anemones need a protein-rich diet. Food enhances their colouration. Therefore, protein-rich seafood such as squid, shrimp, clams, and mussels are ideal for Bubble tip anemones.

Before feeding, bring the food to the same temperature as the tank water. First, wash your hands to remove any soap or moisturizer. Make sure traces in your hand do not contaminate the food or tank water. 

Cut the food into pieces. The sizes should be in relation to the mouth sizes of the anemones. Quarter-inch pieces are suitable for smaller anemones. But larger pieces are needed for large anemones in case they can digest them.   

Use a feeding stick or tank tongs to give them food. Hands also can be used to give food but there is a risk of being stung. 

Slowly place food on the tentacles of the anemone. Bubble tip anemones should grasp food and move it towards and into the mouth. Do not throw the food towards the anemone. 

Feeding frequency

Feeding frequency means the rate at which feeding occurs over a particular period. Normally feeding frequency of Bubble tip anemones is about one to three times a week. But this depends on the size of the fish and the nutrition amount of the diet.

When there is a clownfish in the tank feeding frequency can be reduced. The reason for this is the clownfish helps Bubble tip anemones to catch the prey. Therefore, no need to feed the Bubble tip anemones again and again. 

What should you do After feeding

Bubble tip anemones do not like some food that we give. Sometimes they may spit out these foods. On such occasions, Bubble tip anemones may excrete it as a mucus-like cocoon and hold it with tentacles to eat later. 

These foods may be deposited in the tank. Remove such uneaten food after an hour. Otherwise, rotten food can pollute the tank and cause significant water quality problems.

Bubble tip anemone and clown fish

BTA clown fish

In natural environments bubble tip anemones and clown fish have a symbiotic relationship. That means they help each other as good friends.

This is how it happens. The anemone alone prone to natural predators. larger fish try to attack the anemone and tear their tentacles. However when anemone pair up with clown fish they take care of each others.

Bubble tip anemone provide clown fish a hiding place and clown fish bring food to anemone.

If you have either bubble tip anemone or clown fish alone in your tank, try and introduce the other in to the tank. You definitely see how they pair up easily and become friends.

Predators of bubble tips anemone

BTA predator

Predators are the animals that hunt or prey on other animals. Angel fish can be considered as the most common predator in Bubble tips anemones. 

Angel fish will feed on the tentacles of the Bubble tips anemones. Other predators are more venomous anemones, some marine molluscs, and some species of sea stars. 

But Clownfish can protect the Bubble Tip Anemones from Angelfish and other predators. 

Why are bubble tip anemone dying?

BTA dying

Bubble tips anemones can live long. But the exact or the appropriate age of them is not discovered yet. 

The combination of low salinity, stress, improper lighting, and poor water quality conditions are not favorable factors for the growth of the Bubble tips anemones. These factors even can contribute to shortening their life expectancy.

When the temperature is very high in the environment, Bubble tips anemones undergo a process called “bleaching”. Bleaching destroys the edible algae in the tank too. 

The internal food supply of the bubble tip animals will lose as a result. This converts the anemone into white. The reduction of health in Bubble tips anemones can drive them to death.

Are bubble tips anemone poisonous to us?

Not that much, But Bubble tip anemones can sting you. They have stinging cells called “nematocysts”. Stinging cells pierce our hand as soon as we touch the body of an anemone.

These stinging cells are more poisonous to fish and threaten their lives. But for humans, it usually goes unnoticed. In some instances, it just appears as sticking to us. It becomes alright after some time. 

Do bubble tips anemone overspread?

Bubble tip anemones are one of the easiest anemones to keep. They can propagate easily. But the factors like water quality, lightning and feeding decide the growth rate. 

Within 6 months the anemone can grow up to 4 inches. Therefore, bubble tip anemone shows a moderate growth rate. So, we can not say that as overspread.

Why do bubble tip anemones lose their bubbles?

Sometimes the bubbles of the bubble tip anemones may lose or disappear. There is not an exact reason for this. But some causes may be responsible. 

When the anemone receives insufficient sunlight, feeding and poor water quality conditions the bubbles may lose in bubble tip anemones.

In another aspect when there is a predator, or a competitor living with the bubble tip anemone it may also be responsible for the loss of their bubbles. It was found that when the clownfish aggressively hosts the anemone it also can disappear bubbles. 

With that, we can conclude Bubble tip anemones tend to lose their bubbles when a threat exists to them. When we remove the threat factor the bubbles may develop again in bubble tip anemones.

Can you touch bubble tip anemone?

Yes, when we touch a bubble tip anemone it may sting. But it is not severe for humans. Most people do not feel it or react. 

Only some sensitive people may react to the sting. But that is also not severe at all. Therefore, it is better to wear a pair of gloves. Powerless rubber gloves or Nitrile gloves are good to wear when handling bubble tip anemones.

Can bubble tip anemone kill fish?

Yes, Bubble tip anemones are carnivorous. That means they eat only the flesh of the other animals. They can kill certain types of smaller fish by stinging them up to death. Bubble tip anemones mostly kill fries and the weak bottom-dwelling fish.

But cardinalfish and damselfish can live peacefully with bubble tip anemones in captivity. Altogether the only species that can get true benefits from bubble tip anemone are the clownfish. Bubble tip anemones provide protection and shelter for the clownfish.
