i am setting up a tank that will have corys in it. should i use sand or small sized gravel for the bottom of the tank?
no problem
I'd go for 2-3mm pea gravel, as long as it's rounded, it'll be fine for the cories. My cories hated the sand, and it's a pain in the backside to clean - and yep, it clogs up your filter. It's just not necessary if you get fine gravel - then you can vac up more vigorously, and therefore keep it much cleaner - which in turn is even better for your cories as it'll lower the chances of infections to those barbels
Mine have all been on large gravel, sand, and now 2-3mm pea gravel - and have been fine
