I thought I was going to have a breeding tank, but a couple have surprised me wth little guys. I am culling them out currently and will use what was supposed to be a breeding tank over to a nursery. I will watch and cull them as I see them or let them become tasty morsels like my test guppies did. My question is what to feed them? Should I just crush up some high protein flakes or pellets? I also thought about scraping the sides of the tank for small algae. Someone help a new grandfather, to fish anyway, with some sage advice. They are very small and gathering around the air stone right now. There are about 20 I've caught so far. They sure are fast for such little guys.
