thank you all. it has ghost shrimp in the tank, have tried chppoed night crawlers and it just chews on them and spits them out, and i'm not sure if it is eating the blood worms that i'm trying, they seem to disappear but i have never actually seen him eat any. so i'm not sure. he is very active during the day is this a good sign? it "bounces" up and down along the glass is this good?
