okay so i got my rhom prolly 3-4 weeks, ago, he was really skittish and would just stay in his corner all day/night. Well he is starting to finally open up, i catc him swimming around alot more now and all of the original 10 danios that were in there are now gone. Well, I went to go feed him some shrimp , took off the glass lid and he goes nuts, starts swimming into the wall hitting his head, super fast swimming too. Does he see his reflection or something in the glass or something? he just goes bezerk. any one else have these problems or know what i could do?
