So. I need opinions.
Who's got some experience with dividing a tank? (What sort of dividers did you use, how did you set it up, how big was the tank, etc.?)
What sort of issues did you encounter (fish jumping, dividers failing, over-aggressiveness, stress, whatnot) and how did you resolve them?
How did it affect the way you ran your tank (where did you put the heater, how/how often did you clean it)?
Any things you'd recommend always/never doing?
I recently got my hands on two ten-gallons and I'd like to divide at least one of them-- I don't feel experienced enough with other fish to try 'real' tankmates, but I'd really like to keep more than one fish in it, just because of how huge it is. Hence, OPINIONS. I'd really like them. :)
