Hey all, I'm new to this app so I hope I get the hang of it!! I have 4 black skirted tetras and have had all 4 for a little over 2 years. Recently their colors have been changing... 2 of them are much darker now. In addition to darker fins, their lips turned black. Is this normal?!? The color showed up a few months ago and has been like that ever since.
Thank you!!!
