Hi, I picked up a fancy trio a while back and they are doing fine.
Last Monday I went to my LFS, he had no trios but had a couple of fancy females (no males of that type) the one female was expecting, lo and behold Tuesday am she had like 25 babies. (I put the babies in a 20L, and they seem like they are doing fine.)
That same day an order from co-op showed up with some Easy Fry Food, that really helped with feeding the little guys.
What I did seem to learn was when the female gets that back bend, that might be a sign of getting ready to birth??
I hope I said that right.
I think you might want to go with a fancy trio.
