hello all. just set up a 90gl tank with established rock and substrate so the tank cycled quick. my wife saw a sfe at the lfs and wanted it so he is now in the tank. its been almost 3 weeks and i cant get him to eat. put feeder guppies in on their own. used long tweezers with cut up raw shrimp, and put in gold fish and waited till they died then grabbed with the tweezers and dangled in front of him with no success. for the most part he would just shy back into the rock but today he just stayed in one spot but didn't go for it. my question is, is this normal and when should i start to get worried that he is starving himself? he is the only creature in the tank. i am planning on adding fish very soon so i was wondering if he is just being shy cause there is no other life in the tank.. thanks to all that can help.
