Is 2-3mm Gravel Ok For Cories?

    I have Unipac "Black Glass" gravel in my tank, which is 2-3mm. It doesn't feel sharp to touch.

     

    I'm considering a school of panda cories. Would they be happy on this?

    Thanks!

    honestly i would switch to sand as glass can erode and get sharp over time resulting in cuts

    It's not actually glass - it's just called that because it sparkles :) It's natural gravel.

    orr..oops. FFrom my experience, my cories prefer sand over gravel..they like to dig the fine sand

    I wouldn't worry too much about that. They do prefer sand, but I have black Diamond blasting sand which is really fine gravel, and they still sift through it and dig around :)

    I opened the link and zoomed in on the micro "gravel". Looks like black diamond blasting sand to me. You should be fine.

    I would say sand would be far better, but this would suffice.

    Should be okay, but watch for any damage to their barbels.
