Hey Neal I tried raising some FW ram fry a few times with no luck
I recently bought some german rams from a breeder and he gave me tips on raising them that seemed so simple, maybe it will work on the ponies.
He would put the babies in a tupperware container, just a round 4" one, and just let it float around in the main tank with a air line with about 1 bubble every 2 seconds just for water movement and he would have like 150 babies in it. The reason why this rather than it's own tank it like puting 200 babies in a gymnasium then throwing food in there, they are young and haven't learned to find food or eat yet, so by conentrating them in a small area they learn faster cause food is always floating around in there. And water changes a simple just dip the dish down a bit and viola done new water just make sure your don't swish them out
Now that I know all this think my rams will lay eggs???
