He's also a blenny so he may just be eating micro algae and things we can't see. 30 days is a long time to go without food. Must be getting some sustenance from somewhere

I guess I just see it a little different. I've done alot of breeding of killifish and shrimp and culling is just part of the experience.I totally agree but how do you determine when it is time. Day 1 when he is sick . Day 3 cause he isn’t cured yet? What if day 5 or day 7 he shows signs of recovery
I do agree with not letting them suffer, but there needs to be a point that needs to be reached. The op has not seen any identifiable issues other than not eating. Would you recommend he do that.
I would say he may be fine. Get some black worms if available or buy a clam freeze it and the slice it. Almost guaranteed he will eat,
Let’s hope for the best and see what happens
One advantage though was input from a vet, and with our fish we don't have those expert opinions.Why black worms when he is not carnivorous?
Why not try some kelp or a pea?
I've got a blue jaw trigger that went blind. I've been struggling with this for a couple of months. I've tried everything I can to help him, but nothing gets better. He looks really healthy, but he can't find food on his own. I have him in a 10 gallon tank and all he does is stay under the return nozzle. When I put shrimp touching his mouth he eats. He doesn't react at all to anything approaching his eyes. He never swims around. His whole existence is swimming in one spot. I'm running a 10 gallon tank just for him. I bought some clove oil to euthanize him, but I've put it off for a couple of days.
Never been there myself, but I think I'd have to let that go

Yes, I treated for flukes and velvet. I've tried copper, FW dips, Metroplex and Kannaplex, chloroquine phosphate, and prazipro. I've also recently added melafix.
Triggers are so personable when healthy. You've done all you can though, and if I was a trigger I wouldn't want to be stuck in a 10 gallon and hand fed
Poor guy though.He's also a blenny so he may just be eating micro algae and things we can't see. 30 days is a long time to go without food. Must be getting some sustenance from somewhere

Fish can develop internal infections as well. It wouldn’t hurt at this point to try a course of Furan-2 and see if he perks up.
