This is my bicolor hammer coral. For some reason he almost looks like it is stretched out and not happy. When I first got him, he was perfectly fine and looked extremely healthy just like my branching frogspawn. Overtime he seems to have looked stressed and stretched out and his tentacles seem very skinny. Is there something wrong and if so can someone please help me
