Hey Rachel, thought I'd let you know what I found out from another local breeder that has been successfully spawning petricolas for some time. He takes a clear plastic cup and fills it with marbles, then he puts a pot that fits well upside down over the cup. The petricolas go through the little hole that is the bottom of the pot (top of the breeding hut) and lay the eggs in the marbles. He uses the clear plastic cup because he can periodically pick it up and look at the bottom to check for fry/eggs easily. I thought that was a great idea! Might just give that a try with my petricolas...
