OK, my thoughts have been pretty spastic on this area over the past week or so, but Im trying to decide what kind of bottom feeders to get for my tank. it's 46 gallons and has 11 tiger barbs in it. my original choices were cories or yo-yo loaches, and I thought i wanted cories but then realized my substrate isnt really right for them, and ill probably start up another tank later on to put cories in (something a little more peaceful than the tigers...). is this the right move? what else can go in there with the tiger barbs? are there any particular catfish species that would do well in a tank that size with its current stocking level? argh, this is driving me NUTS!
