>> I'm just guessing that it can happen with Apistos. An angelfish breeder who spoke at our Raleigh aquar conference a few years back noted this phenomenon, and personally I've seen it with Julidochromis transcriptus. I gave some Julies (an old strain I've had many generations) to a local friend who uses white pool filter sand or bare-bottom tanks, and his offspring have greatly reduced (and paler) black areas than mine do. (I use brown, gray or black sand in all tanks). Do other folks have experience with this? Does normal pigment develop later if adults (raised from birth on a light bottom) are moved to a dark bottom?
>> Melanochromis: Interestingly, I may be having problems with the vertical bands on the fish. The earlier Inka I bred don't have dark vertical bands like their parents. The bands are very faded and difficult to see. I don't know if the batch will grow up to be without bands as well.
>> Gerald: The substrate color can affect their pigment development. If fry are raised on white sand or a bare glass bottom their melanophores might not develop normally. I dont know whether this effect is temporary or permanent. It might depend on their age and duration of "dark bottom deficiency".
>> Melanochromis: Wow, you sure that's possible? This is a new knowledge to me. Never thought of it before. If this is true, I'll probably have to adjust so many things :-(
