OK.  I'm not new to fish but I have'nt had live plants before.  I heard Seachem's Flourite is the bomb for planted tanks so I got me some (two 15 lb bags) and but it into a recently vacated 20g (after spending the better part of one day (only slight exageration) cleaning the flourite but that's a whole other thread).  Well I was hoping to keep a nice group of corydoras in my soon to be lush and glorious aquatic garden but the flourite is pretty sharp and seems to be what all the lit recommends against when it comes to cories- " Prefered substrate is river sand but smaller smooth pebbles are acceptable".  Anyone with experience keeping cories in a tank with flourite?  If I top the flourite with smooth pebbles would they keep their barbles?  Would bigger ones dig down through to the rough stuff?

My Corydoras love my flourite.  I say that because their barbels are all nice and long.  I used to have them in a tank with larger river rock, and none of them had any barbels.  I moved them into a planted tank with all flourite and now they all look great!

i had that problem when i used river rock too. larger substrate leaves more room for old food to decay adding bacteria that will cause the barbs on a cory to rot off.try and see if they like it.if not have a place to put them so they can heal.cover it with a layer of fine gravel and sand,maybe this will work to kill two birds with one stone.florite for plants,proper substrate for the corys
