yah unfornately the gramma died
watch out for that nasty ich! and a cleaner shrimp would be a great idea because it will even clean the parasites off the fish! i have a "blood shrimp" or a fire shrimp and it hasnt made a cleaning station yet they dont always do i guess. but ya thats going to be my next step a cleaner shrimp than from there a whole lot of coral! do you have any other tanks or just the bio cube?
