Well, I lost the red-tailed shark last night. Two nights ago he decided to find his way into the inside of the fake white rock. I thought he might just be exploring or hiding for some reason, but I think he got stuck in there. I finally got concerned last night and got him out, but he was looking rough. His tail fin was really shabby – about half the length it used to be, his color was washed out, and there was a large white rash on his side. I tried to feel him, and noticed he had trouble swimming, and would rest on the gravel a lot which he never did before. Around midnight, I noticed he wasn’t moving any more, so he got the Royal Flush treatment.

Oh well, it was fun while it lasted. Guess I need to find a way to plug up that big opening in that rock so no one else gets stuck.
