Yeah you're right dewdrop, i'm a big fan of the Acei to, and there is no reason at all to get rid of them. i retract that commenntI wonder why Gibbs said lose the acei. I love my acei & I'm trying to get a longer tank for them. Since I got the acei alot of my other fish swim up higher in the tank too. I think they really make a tank come alive.
