So the fry in my 75g are doing well and have been eating egg yolk. So, my uncle gave me an old 10g. I have a heater but only have hob filters or air stones. How can I use these for a fry tank. I want to pull half of them out of my display tank and leave the others since the parents are doing so well. I may end up killing them before they die in the community tank. I figure I will see who can keep them alive the longest.
