beginners, certainly not to those keeping a community tank. This
fish should only be kept with other aggressive cichlids. The
coloration for adult, dominant males is near black and appear
almost totally black when breeding. There are a variety of
geographic variants of this fish; some males in breeding dress
show several bright blue sparkles on their flanks which can be
very pretty. One thing the aquarist will notice with these fish
is that they change color rapidly! Interestingly, males can
change color to look almost exactly like the females and, in
fact, females can quickly change color to a murky black. Why
would this fish adopt this color changing ability? I found my
answer in Ad Koning's book "Malawian Cichlids in the Natural
Environment". Pseudotropheus crabro inhabits cav
