About three and A half weeks ago i purchased a Purple Queen Anthius, I Had slight concerns about him but the lfs store were I purchased him assured me that purple queens were very hardy also assured me he was eating, well prior to this I had never had problem with them, after getting him home aclimating him witch went well. He was out swimming about that same night. Now after getting him all settled in did research on him found they are very difficult to keep. Also hard to get to eat. Well it has been three and A half weeks Havent seen him eat a thing, he does come out every day. when I place food int he tank just ignores it. he also has a red mark on the center side of his body down the whole side this has just developed. I have tried flake food rods original formula, rods myisis and brine alsong with formula two. Any suggestions.
