I just got a small gold nugget, and its the second day now and he's still not eating! I tried veg, pellets, bloodworms - everything! He's hidden under my juwel filter and its difficult to get food to him, but even if there is food near him he still wont touch it. what should i do?why wont he eat?when he did come up to the glass i could see that his stomach was hollow, kind of sunken in i think they didnt feed him when they sent him to me by post.im worried now.
