Yellow Clown Goby Not Eating

[Snaz]

I bought a YCB and it withered away after two weeks. I tried every food under the sun, the only thing he seemed interested in was mysis cut up but he would just spit it out.

After his stomach caved into nothing he got these weird bumps in his skin almost like tumours but they would change shape. I put him out of misery.

I think I will try another one day but I will make sure I see it eat before I take it home.
