Thanks for your reply. I think I'm going to give up my loaches though, as they seem to need a much heavier current than Cichlids or other fish I want can handle. Plus, I'm learning from another Clown Loach forum that they really aren't compatible with Cichlids in the long run, especially Oscars which I was thinking of getting. I'm planning on getting a 125 gallon tank, but I don't have it yet, so I still have time to see what I want. Right now I have a 12 gallon tank with four Harlequins, four Zebra Danios, One Blue Gourami, one 1" Rubber Lip Pleco, and of course my two small clown loaches (which I am taking back to the lfs).
