Not really, sen grows faster than cory catsThe sen will eat them? That will be a LONG time I bet. This sen is 3".
Not sure, I'll have to do a little research.
I'm really loving the 75 gallon. All parts of the tank are being used and it feels full and complete. It's not complete but my 125 is just so bland in comparison. I guess because it's so big and I have 5 baby polys in it and some rocks. I guess this is where patience comes in. I'll try to find a couple large pieces of wood for the 125 and tie plants on it.
