Baby ocellaris refuses to eat

[ACBlinky]

I recently purchased a pair of tank raised ocellaris clowns, about 3/4" long. One has adjusted nicely, recognizes the pipette I use to feed and eats fairly well (he's only taking frozen, no pellets). He's got a nice round belly and a happy attitude. The other was semi-interested in eating initially, though he spit most of it out, but even with Entice, garlic, and my efforts to find something he'll like he's completely refusing to take food now. Being a baby with no reserves, he looks dreadful after a couple days without food, and I'm at a total loss.
Water paramters are fine (NH3/NO2/NO3 all 0, PO4 0.1, pH 8.1, Ca 380, 8dKH), and the corals and other clown all look well. Would it be kindest to euthanize him, or is there something else to try?

How long have you had them? One of my perculas took 4 days before I saw him eat and he was tank.

I brought them home last Sunday, so it's been less than a week. He's incredibly thin, and I just can't seem to tempt him to eat. They've got no competition for food, it's just them and a little clown goby in the tank.

Thats stange for a clown to refuse food. Most eat right away. Just try some differen't types of food. Nothing else really to do but find a food that he will eat.

Have you tried cyclopeeze or live brine shrimp?

 

[ACBlinky]

I've tried:
Frozen mysis
Frozen brine
Frozen plankton (chopped up)
Frozen 'marine formula'
Frozen Hikari Mega Marine Angel Formula
Hikari Marine 'A' (crushed) and Marine 'S' pellets
bottled zooplankton
Cyclop-eeze
and all of the above with garlic or Entice. I've tried feeding in the morning, midday, and even after lights out.

With all the experimenting I'm obviously overfeeding, so I'm keeping an eye on the water parameters and doing daily water changes (takes about five minutes, doesn't require me to shut off equipment or stick my hands in the tank and doesn't seem to disturb the fish).

I think the poor little guy must be sick - he's swimming head-up and seems unaware of his surroundings now, IME that's a very bad sign.

A very bad sign, he/she probably is too stressed out. Good luck though.

I want to thank everyone for their input, sadly I think I lost the little guy last night I say 'I think', because there's no sign of him at all. He's not outside the tank anywhere, I checked. There are four Nassarius vibex snails, a small blueleg hermit and a medium-sized Hawaiian zebra hermit in the tank. I guess it's possible that they consumed the body overnight, he was pretty tiny.
I did a 2g water change to keep the water conditions pristine for the remaining clown, who looks just fine so far - he's starting to act like a clown, he attacked the hose when I put it in the tank, I take that as a good sign
