My larger male has me so confused as i dont think hes a blue varient anymore. his colors are going through this bizzare color stage where it was before gray body blue fins its now gold/orangy body and orange on face wormings and blue fins. The pics dont show it that well. In the pics is also my only female, his sister and as you can see they are paired off and trying to breed lucky for me that wont happen in that tank. The last pic is of my smaller male who use to be yellow but has now changed again. And as for the baby nic male he didnt change much so i didnt add his pic. So can anyone finally say if my largest male is nic or costa rican?
