While it was done in cruelty, I've seen people remove the lips of pirhana without major complication.
I just inherited a deformed goldfish with a similar defect to this: (not my photo)
He cannot open his mouth, his lip blocks the entry of all but the tiniest food and he is clearly underweight - likely from this defect alone. I've seen fish with no lips eating fine and living well. I just wanted some feedback on whether or not y'all think removing a portion of the upper lip is a reasonable modification to allow food entry.
He's a derp, but now he's MY derp and I want to do the best I can for him...
