Quick question, I am rescaping my African tank from gravel to sand, as well as adding rocks, and I'm planning on taking my fish out of the tank until the tank is set-up, and the cichlid sand settles. I was planning on going out of state over the weekend, and was thinking of putting all of my fish (about 20) into 2 styrofoam coolers, rescaping the tank, and putting them back in when I get back on Sunday. The fish will be in the cooler from Thurs around 5 pm, until Sunday night. I've cut off feeding to avoid them pooping in the cooler too much, which I think will lead to nitrate build up. Do you think they'll be OK for that amount of time in the styrofoam coolers? I'm using fresh, de-chlorinated water. Any advice would be greatly appreciated.
