Hi Matt
congrats on your spawn!

If you keep a community tank its very hard to keep fry alive. It seems that all the fish will find them a meal to go after. I dont know what size tank you have now, but if you can do it, why not move the kribs, and pot of eggs to another tank? Or if you also have the room to move the rainbows, you can always move them. The chances that your fry will survive in a community tank is slim. I dont know enough about Kribs to give you more advice and hopefully some Krib owners will be along to give you a hand.
