i tried to catch tang for r.allard and he ended up on his side on the bottom of tank behind some rock. he got majorly stressed out and we left him alone. i added the ick attack and it went away for 2 days, i am afraid to use it agian though. the tang is covered in ick and does not look well at all. im trying to treat him without having to take out all my rock to catch him. going to try a cleaner shrimp tommorow.
