I have decided I really would like some Corydoras in my tank. I have just one small problem. I have eco-complete for substrate. I have heard this is a problem for them as it is to "ruff".
So I was thinking this, I would split the tank as far as substrate goes. Half sand and half eco-complete. In the front part of my tank i really don't have that many plants that are heavly rooted soo I think I could get away with sand there and leave the eco in the back. I found some black sand the other day at petco that wasn't that much was thinking of using that so as you wouldn't really be able to tell the difference at a glance.
I thinking i don't really want a straight line between the two substrates but maybe something that "flows" a little more. However what do I use to separate the two substrates? Rocks or maybe sticks? ALso would black sand be okay or something more of a tan color? Any suggestion or thoughts on this?
