We have a breding pair set up. I was about to give up hope on them until I came home one day and my wife told me they did it.
They spawned in a cave with 7.2 ph and near neutral soft water, which I was surprised. They just spawned and I didn't know until the female was guarding the cave. Now they won't stop spawnig, I have 2 10 full of fry.
My name is Jay, My wife, Barb, and I have a modest little fish room in our basement(about 166 tanks and 4- 55s,1- 75 and 1-46 Bow front in our living room, and 1-30 gallon in the bedroom) all in all about 2000 gallons of tanks.
