The divider I bought at petsmart is a piece of crap. Really, this should be pretty straight forward. A piece of plastic that divides the aquarium. But the plastic side part is cracked, and it isn't tall enough, and it also twists so it doesn't seal the sides completely. What ended up happening is the tiny gap on the side let fish through, and they would get stuck on that side.
I ended up netting out all of the fish and putting htem in my other 55. Its really crowded, but so far my Green Terrors are being pretty good sports about it.
Hopefully I didn't stress out the jacks too much. The male is hiding in his little cave, but the female is still guarding the eggs. Should I turn off the lights?
