BABIES!!! Gotta love em!!
I don't like using breeders nets or boxes....makes a lot of work, and often times it is harder for them to find the right things to eat....If they have survived this long, it might be possible for them to live in the tank, if you beef up the amount of cover they have.
Do you have java moss? Lots of plants, rocks, shells, driftwood? Any thing they can dart in and out of and find cover?
Water Sprite floating is also good, as it develops roots that hang down and the fry can hide in it.
This lets them feed the little scraps of food that drift around, and graze on algae from the plants they take cover in.
I have never had babies from eggs, and do know they are a whole lot smaller than live bearers......but this is how I raise my platties..It works fine.
