I have had them before mine love baby brine shrimp I used to hatch them and about 50 survived out of about 100 but the filter is the biggest issue there not good at fighting the current and so I used a bubble filter and some angel fish are great parents so if you have the adults with them then they should do the work for you but don't go and put them back in with the fry because then they won't remember and eat them o and congratulations on the fry your almost there I put mine in a ten gallon tank then moved them to two 30 gallons
