Well I just think Tiger barbs are just too much pf an obvious choice. I really like barbs though because they are all so colorful, quick, and hardy. Also the danios at my LFS are the ugly longfinned ones and they wouldn't go so well with my sev I don't think. Anything out there that cleans up algea really nice. I have not had a pleco in the tank for over a year but I ocasionally get some algea. I would like to add some darker colors to my tank because the sev is bright yellow and red and the sand is white. Hopefully that helps you out a bit more. Sorry I am being such a pain in the *** but I really want to do this right the first time and not waist all that money.
