Bubble Fish and black stripes on tail?

Question

Im just wondering, my fish has black stripes comming off his caudal fins (back fins) is that normal?he is gettin golder and growing really fast so im just making sure hes not sick.

Answer 1

Sounds like he's in the process of his colors changing a bit. You mentioned he's getting golder, it's probably just some black developing in the fins and nothing at all to worry about.
