+1, great info.
mbuna like labs and zebras get to like 5-6in, auratus can get 7+, fuelleborni and rusty 7+, iv seen a 7.5 in bumblebee cichlid. as mattrox says, with overfeeding and a biig tank, they can grow much larger. same as with a smll tank and less food, they can stunt and stay dwarf-like.
mbuna can breed from about 2ins, but usually at 3.5 to 4in. my smallest holding mbuna was 2.5 in and gave 16 fry, so not bad lol.
do you have mbuna? x
