I Anybody else keep different Melanotaenia species together? Do the fry survive if you don't remove them or remove the eggs?
I keep many Rainbowfish species together in one tank. Usually the fry get eaten so fast that you won't see them. However, if you look closely at the water surface, you may get lucky and see some fry.
When I was breeding Red Rainbowfish (
Glossolepsis incisus), I netted the babies from the breeding tank and put them into a 5 gal that I had set up for raising these babies. I had set up the 5 gal tank with plants from another tank. Those plants apparently brought in eggs from Neon Rainbowfish and one Turquoise Rainbowfish. Now, I have a group of Neon Rainbows, and one Turquoise Rainbow (the few baby Red Rainbowfish I netted didn't survive).
Breeding Rainbowfish is fun. Sometimes all you need is to have a plant from a tank where Rainbowfish are spawning.
