nah, no trouble, Lotsa fun though, from what I have read they will breed in a well aged tank, with the right conditions, which happen to be about the same as what I'm running my leopard fish in (and I doubt they will eat the fry as the tank is seriously full of plant for hiding places), Just need a bit more soft green algae growth, and an infusoria culture.
If I have to play around, then even more fun!!!
