The RD i got a week ago is always hiding. I put a clay pot hoping he would us it until he got larger so at least you could still see him But no he has dug under it and stays on his side squeezed under it and the tank bottom. He comes out to eat and moves around a bit after eating then disappears again. I’m thinking about removing anything he can get under because I can’t stand a tank that looks like there is nothing in it. I also thought about moving the dithers from my 75 to the 55 to see if that would help because my severums don’t need them. What does everyone think? The last straw would be to take him back (which I don’t want to do) and get a different one thinking it’s just this guy is a scaredy cat.
