that is a syno eupterous.or featherfin catfish.this has happened to a few of these guys and it comes from poor water quality or malnutrition.if u solve these problems he will gain his pigment back.
You serious?! That discolouration was caused by bad water quality?! Wow. Never seen a eupterus look like that....ever! Learn something new every day!
Hope he does well and regains his colour Ryan. I honestly had leanings towards some sort of albinoism happening in his genetics but there ya go.
P.
No, the discoloration is caused by water quality issues. It's not a natural thing for those fish to look like that, poor little guy. If you can solve the water issue...he should color back up fine. Albinos have eyes, in all the albino strains.
