It turns out that the 75 gallon tank I resealed has a leak. I came home today, and teh entire fish room was flooded with almost an inch of water, and there were only a few inches of water left in the 75. Thankfully, the haps were OK. I moved them into the 40 gallon tank with my flowerhorn, and used some matala filter media as a divider. Once I get all the water off the floor, I'm going to be setting up the 55, and I'll keep the haps in that.
