what could i breed in a cycled 2 ft tank?the fry will be feeders for my needle fish and rbp so the bigger the better.i dont wanna seperate the fry either so good fish parents im after.
Convicts, perhaps? They breed like rabbits and exhibit great parental care. Otherwise, stocking it with loads of female guppies and one male, with lots of hiding places for fry, or as CFC suggested, kribs breed easily once you've got the conditions right.
The tank would be a bit small for convicts, males of which can reach around 6 inches and are highly aggressive when breeding (which is always), it would be very likely that the female would end up dead or very badly beaten should a spawn go wrong for any reason.
