iv got a 20 long community tank and i was thinking of adding some hillstream loaches. the thing is hillstreams like a good current, and im afraid some of my other fish might not. i can always set up a 10 gallon and remove the non-current loving fish to it to make room for some new additions. so right now iv got a betta, ember tetras, black kuhli loaches, cory cats and a banjo catfish in the 20 (i know, it fully stocked... im aware as iv been told a million times its quite full). which of those would need to be moved to a still water 10 gallon? the betta is obvious but what about the others? oh and the current would be created by my fluval 3 plus, so i wouldnt need a powerhead.
