Crimson-spotted rainbow fish

Postby Litoria Alex » Mon Jun 11, 2012 9:30 am

We are putting in a frog pond and would like to have fish in it also. I know white clouds are a definite no, but what about crimson spotted rainbow fish?(melanotaenia splendida Fluviatilus)
Does anyone know if they are safe with tadpoles And frogspawn?
Thanks,
Alex

Sorry about the delay in answering, I haven't looked in here for a couple of weeks or so. I have pond that is about 3.5m x 2.5m x 0.6m deep that has two male crimson spotted rainbowfish in it. (Two males so they cannot breed). There does not appear to be any problem with predation, or at least if the fish do take the odd tadpole, it makes no noticeable difference to the tadpole population of which there always seems to be plenty in the warmer months. They take complete care of any mossies - never see any or any wrigglers and we don't feed the fish, they live off what grows in the pond.

Thanks, sounds like these are the right fish for our pond then:)
Do you think it would be ok to breed them or would they overpopulate?
Also, is it easy to tell males and females apart?
Thanks for your help:)

They may well over populate if you allow them to breed and under those circumstances you will probably get predation on the taddies/spawn. The males have darker edges to their fins, the body is "deeper" (or taller, if you like) However, the smaller (younger) the fish, the harder to sex them. Generally speaking if you want to sex them, go for males as while small males can look like females, once they begin to show sexual dimorphism, it's easiest to pick the definite males.
