First post and gotta say this is a great site!
I have a 10g tank, some plants, a statue and a tree stump cave thingy. I have 4 ghost shrimp, 3 peppered corys and 4 sunset platys. After the tank stabilized I introduced Nick Saban, my red vt male. He explored and seemed very happy, ignoring the other fish unless they came near the cave stump and he'd chase them off. After observing for an hour the wife and I went to dinner.... 3 dead corys upon my return. Platys seem all right, he's ignoring them and the shrimp.
Any advice on another algae eater? Perhaps more than 3?
