I just put a cleanup crew into my 20 gallon and everone seems to be happy!! except i have 2 mexican turbos, and one, that's about twice as big as the other one, is stuck to the little one and won't budge...... The little one can't move as the big one is latched onto his shell? I tried to pull him off but to no prevail he won't let go and I don't want to hurt him... I don't want the little one to starve though, is there a way to get him off?? thanks for all your help guys, this forum is my savior
