I have 4 randomly selected red zebra juv's. I initially was afraid that I had 1 m/3 female because 3 are smaller and bright orange, and one is larger but a very pale (almost peach) color. However, the larger/paler one is always gaurding a cave- chasing all other fish away and is constantly chasing the others around. I have seen the pale one circling with the other zebras several times. One time I thougt it was holding egss because about an hour after I fed them it spit a few small things into the water and gathered them back up but maybe it was poop or something, IDK. Anywyas, I guess my question is can the male be more drab than the females?
