Advertisement This tarantula (A. avicularia) keeps having trouble, and now I'm a little freaked out. It has been weak and inactive for a while. It hasn't eaten anything for months and lately its lost some weight (visible in photographs I will upload shortly). I tried putting it in a small container with a cricket and a super worm, which it killed but did not eat. Then I gave it some water... Bingo, it drank! I was happy because I hoped I had found the problem, but now something is wrong. Its been sitting over its water dish for a bit (where I put it), and now I noticed there is white foam on its face, and a white substance that has sunk down beneath the water where it was sipping. Its almost as if the tarantula threw up. What does this mean? Is my spider sick? It certainly hasn't been behaving normally for a while now. All my other arachnids appear just fine, this has been the only one that consistently has problems.
