Diet & Feeding
These Rainbowfish are easy to feed and have no special requirements when it comes to what they eat.
Provide them with a varied diet of micro pellets, flakes and granules as well as small frozen, live and freeze-dried foods such as baby brine shrimp, Cyclops and Daphnia.
The Forktail Blue-eye can be bred in groups or pairs. They will generally become sexually mature when they are around 3-4 months old.
A densely planted aquarium of java moss or equivalent is advised for breeding purposes as it will make the fish feel more comfortable.
The male will display a show by swimming back and forth in the aquarium while keeping his anal, dorsal and pelvic fins in an erect position.
He can be a little pushy towards the female, but if he becomes aggressive, you should separate them because they are more than likely not compatible, and the female may get hurt if she is made to stay with him.
