Good point. The Albus are very mild fish from what I can tell. I see no signs at all of them fighting for position. I can only tell the dominate male by the brighter colors.
My wife went looking for pots and didnt find much that she wanted. But, she did find something. I dont really know what they are. They are made of sinking clear plastic. Smaller than a Kleenex box, but bigger than a box of cards. They are stackable. They already have holes all through them on the sides. Open tops.
When stacked, they are like little fry apartments. We have three of them, but I may get more.
I think I am going to use these and then pile some slate around them so the fry will feel more secure.
We'll see what happens!
