Update. So he does not eat alot. He has ate maybe 1 or 2 sticks in the past 3 days. I've been doing this hobby for awhile and this is by far the most frustrating fish I've ever kept. He's been in the tank for about 10 days now and has been acting the same since he's been in..I blacked out all the walls for him, water is tested every two days. And is perfect. Temp is 80-82.. all he does is hide behind a filter all day. Doesn't want talapia , krill, can't feed him red worms bc they don't float, he is scared of everything that touches the top of the water . I tried holding it with tongs he's just scared of everything. My luck to get the worst one outta the 30 my LFS had lol its getting very frustrating and extremely boring keeping this fish its unfortunate and don't know where to turn with this guy.
