My 10gal is setup at the moment for a substrate sifter. Thats the main fish i want in my 10gal. I was thinking of a yellow clown goby since they stay small and give off a nice yellow color that i like. Are they good sand sifters? I really would like to add a pair of perculas or false percs with my goby but do you think thats pushing it pretty far? tomorrow i will be adding the first of my CUC, im thinking 3 ceriths and 1 turbo? too much, to little?
