Yeah they are going to eat them unless you setup a tank for the fry.. On hatch night u would then just transfer the pots with eggs into their separate tank away from the parents.. I don't think they survive in a display tank because of so many variables which include proper food for them to feed upon, flow will most likely be too much, skimmer, pump and overflow box will probably kill the remaining that don't become lunch for your inhabitants.. On a side note nice looking pair...
