Copperband Fasting?

So I’ve had this copperband for about 2-3 weeks. He was eating great when I got him, he needed some time to eat in my tank (about less than a week after getting him). He was eating super agressively. Now he won’t eat. I’m wondering if anyone has had problems with copper bands eating then not in the same environment. I hope he’s just not hungry but it’s been about 2-3 days and I’m getting concerned. He’s gained weight since I got him but now I feel like he’s lost some in the past few days.

The thing is I got him eating super aggressively in this particular tank with the same tank mates, he’s just suddenly stopped eating. I haven’t had any param swings, new tank mates and anything else change. He’s eating mostly brine but a little mysis. I’ve tried masstick and clam but he doesn’t touch. Did not qt him, no symptoms but he does seem to be glass surfing but it wasn’t as bad as when I got him
 
Is the fish picking at anything on the rocks? Is another of the fish picking on him?

IMO with Copperbands they can be difficult to maintain long term sometimes.

ETA - What are you feeding him?

He is picking a lot at the rocks. my yellow tang bothers him a bit but nothing concerning.
Ive tired bloodworms, 2 brands of brine, 2 brands of mysis, clam in pouch feeder, masstic and I have live black worms coming. he eats brine really well before though

Brine shrimp aren't very nutritious. For some other choices, Download then read, the Fish Nutrition document.

I've raised several Copperband fish since in the hobby. I had two reach the size of a dinner plate. Training them to eat when they are in quarantine, not bothered by any other fish or 'distractions' works best for me. Once in the community tank they may find it difficult to compete -- they are slow/picky eaters.

A fish eating then stopping usually indicates a problem: water quality, tankmate bullying, parasite(s), disease, etc. There is even a chance the fish was caught with cyanide and if so, will likely perish in a few weeks.

I’ve gotten him eating agressively again. But he will absolutely take nothing but sanfansico bay brine shrimp cubes. I think I didn’t seal my large brine shrimp slab well and the fridge air mingled with the taste of the brine which stopped him from eating. He would happly take a bite then stop eating. He was off put by the flavor. Since switching to cubes he’s eating well as ever. I’ve also tried selcon, garlic and lrs fish frenzy, he doesnt like the taste of any of the supplements and won’t eat them. Even though he’s eating well he seems to be getting skinner. I’m feeding 10-12 cubes a day of brine but apparently that’s not enough

I am well aware that brine is terrible nutritionally, I usually only feed mysis but bought brine just for him

I’ve been trying to get him on healthier foods but he wont take it even if I mix the foods he knows
 
Try mixing the brine with other foods. Start with a large % brine shrimp, then keep lowering the %. Also, try other frozen pods to mix with the brine shrimp.

Good luck!

I have he just picks the brine out I’ll try again tho.
 
I use a .15cc scoop, the kind that typically comes with test kits or meds to mix brine shrimp, mysid and calanus and sometimes pellets or flakes in a small dosing container like for pepto or cough medicine. I make a paste with some tank water and can target feed my copperband. If other fish come by just lift it out. I usually spread some food around to keep the other fish busy so its easier to target feed the copperband. When travel I use a auto feeder that drops the same food(dry obviously) into a feed ring and he's able to get food since it's concentrated in a small area.
