I have a new melanarus wrasse, still in QT (cycled tank with LR and sand for sleeping). This guy sacks out at 3 in the afternoon, and comes out sometime in the early morning ( he is usually out swimming when I check on him at 5:30 am). The tank doesn't have lights but I keep the room lights on all day. What are the chances his schedule will change when he gets to the display tank with lights and other fish? I'm not worried, he is eating well, etc. I would like to see more of him though.
