Yellowfin Flasher Wrasse size
These are small fish and the maximum length of them is 3.1 inches (8 to 8.5 cm).
Yellowfin Flasher Wrasse tank size
Since they are small fish the minimum tank for them is 50 to 55 gallons tank. They need quite a large space regardless of their small size.
How many Yellowfin Flasher Wrasse should be kept together?
Since they are small and peaceful fish only the size of the aquarium matters for the number of fish that can be kept in the aquarium.
However, it is always good to add only one male to one aquarium. Preferably, one male can be kept with four to six female wrasses.
In the wild, the Yellowfin flasher fish likes to swim near reefs and rocks. They get protection and safety from reef slopes and rocks to avoid larger predator fish.
In the aquarium, they like being near the bottom of the tank. They prefer sandy bottom and live rocks. Make sure to have enough sand in the bottom of the tank as they like to play with sand.
It is good to put plenty of rocks and stones in the aquarium to provide them with hiding places while keeping the space they need.
They are diurnal animals and therefore need to give plenty of light during day time. It is good to have an additional light source if the aquarium does not get much sunlight.
Although they are peaceful and friendly fish, they do like a large tank. Therefore, make sure to put them in a tank of at least 80 and up to 200 liters with plenty of their own space.,
Like many members of the wrasse family, they are good jumpers. Therefore it is a good idea to set a canopy on the tank.
However, they can detect small gaps in the lid and jump very accurately through them. These little fish are known as escape artists and therefore some experts suggest a roof or lid is not enough to retain them in the tank.
They suggest putting a layer of netting below the tank lid to make sure that they can not jump from the tank.
They are considered by experts and enthusiasts to be quite reef safe and will live in harmony with everybody except micro-invertebrates.
Water quality condition
Water quality is one of the main factors that affect the health and wellbeing of fish. Therefore, need to ensure that water keeps circulating and moving while maintaining the quality of water.
As they are tropical fish who lives in shallow water, the water of the aquarium should be set at 22-26 degrees Celsius (72-78 degrees F). The pH should be in the range of 8.1-8.4, while the salinity at 1.020-1.025.
Regular filtering is important to keep the above conditions. The selection of the filter type is another important factor.
As they are small fish they can trap in the filter and pipes. More on, need to observe the tank and the filters regularly if you planned to introduce fingerlings to the tank.
Yellowfin Flasher Wrasse breeding
Yellowfin Flasher Wrasse male or female identification
The yellowfin flasher wrasse is sexually dimorphic, which means the males and females of this species can identify easily by just looking at them.
The males are bestowed with more colors than the females. Though both males and females own orange, red, and yellow, the males have bright colors than the females.
The males of this species are easily identified by characteristic blue flasher streaks that highlight when the fish are excited.
The pelvic fins of the males are white or blue and they have pink caudal fins. Also, the males have elongated dorsal fins which are absent in females. The females are orange-red with a black spot on the caudal fin.

Yellowfin Flasher Wrasse breeding
The Yellowfin flasher wrasse fertilizes through spawning. During spawning, both fish will swim rapidly upwards in a water column while releasing the eggs and milt.
The females of the Yellowfin flasher wrasses release 1000 eggs into the sea when they reproduce in their natural environment.
The eggs get fertilized with the help of currents and the fertilized eggs are carried here and there by currents until the fry are free swimmers. Then they move to the bottom of the sea as they love to be at the bottom.
Though it is not technically hard to breed them in aquariums there are no records for the breeding in aquariums.
This is because they need a very large and tall aquarium as they spawn with pelagic eggs. More on, they need a large room for their natural breeding dance and spawning.
Anyway, if you try to breed them, the ideal situation is putting one male with more than three females in a harem.
