Well, I made some big changes today.
When I checked on the babies at dinnertime last night, they each had a tiny white edging on their fins and everyone was hanging out at the top in the salvinia roots. Immediately I recognized the preliminary stage of fin rot. Something that's almost impossible to diagnose early in adults was easy to see on those tiny translucent baby fins.
So that was my better-late-than-never clue that it was time to move them into the "big kid" tank. The 2.5 gallon was just too small for 25 growing babies. Using the turkey baster to pick out food bits and do small water changes just wasn't cutting it. I had a 10 gallon lying around (handy!) and this morning I pulled that out, dropped in a large sponge filter with attached powerhead, and moved everyone over. I added 8 rounded teaspoons of aquarium salt as well, to help the babies recover.
Since I was adding the salt, I knew the baby snails couldn't move into the 10 gallon. So they were moved into a breeding net in the big tank.
It's been about a half hour since the little ones moved, and already they are acting much happier. They head up to the top once in a while, but most of the fry are swimming mid-level and checking out the new sponge filter, the plastic plant, and all the extra room! The powerhead creates a lot more water movement than just the elite mini had been doing. They're still getting used to that, but the added oxygen in the water seems to be helping them feel better.
I'm expecting a growth spurt with the move, both in the fish and the snails. From previous experience, I've learned that the sooner babies can move into big tanks, the better. Nursery tanks are good until they're easy to spot, easy to feed, and easy to net. After that, big tanks are much better. So I'm excited about the move. I'll keep you all updated!
