hahaha.... That's funny. I guess I will just give up cories now. Took me a while to get this carpet. Really don't want to ruin it.You don't have to worry. If you have cories you eventually will have bare substrate. I wouldn't ruin your nice carpet with cories. If you want cories I would remove the carpet in one section and add sand, but then they will still mess it up. If you do pygmy cories they don't root in the sand and will swim mid-water. I think that's your best option.
