    I've had river rocks (the kind you get in the crafts section at Walmart) in my tank as a substrate for several months now. Since I've finally upgraded to a 10 gal, I want to go ahead and get 3 panda corys. I'm a little concerned though since I know their "barbs" are sensitive and people typically recommend sand for them. I really don't want to change to sand if I can avoid it. The rocks have been tumbled so they have a smooth surface. Will they be okay?

    Id say it would be fine, I keep my cories in tanks with regular gravel and they are ok.

    I'd say fine also, with one caveat: size. The pandas can damage their barbels by pushing the rocks around to scavenge for food.

    Should be okay. I would keep the level low, though, unless you have plants. No more than 1 inch IMO.

    Keep us posted! And we LOVE pictures around here, don'tcha know?

    river rocks are supposed to be smooth, so that part of it shouldn't be a problem.

    The most important part seems to be that is is smooth with no sharp edges.

    They will be okay, but I would recommend you keep an eye on them for a while. They are used to sand, but gravel will work, so if they do loose a barb, or fin, pay close attention for infection... these guys tend to be VERY sensitive. Hope this helps!

    Good to know! Thanks everyone for the quick and helpful responses! :;th I'll be doing a close inspection of the rocks this weekend when I do a water change but I'm pretty certain they are all very smooth. And I do keep a low level, just enough to cover the glass but not really be piled on top of each other.

    Oh and don't worry, pics will soon follow ;)

    I heard that it is not because of gravel, it is because of nitrate level too high. Any thoughts?
