Hmmm, update! I have three healthy Nematolebias whitei albino fry from the eggs I got from Dennis, and will be re-hydrating the peat shortly to see if I get any more. I have had one more (healthy) biassa fry hatch for me, he's gone missing in my java moss at the moment but will be feasting on brine shrimp tomorrow. Still a couple more eggs with eyespots that haven't hatched yet, but I haven't gone looking for new eggs recently.
The air conditioner continues to be an issue because our rooms are stuffy if we don't turn something on, and I think my one roommate believes that the colder she turns the thermostat, the harder the air blows into the room. I woke up one morning to about 50 degrees outside, and it was colder in my room than it was outside. I turned it back to a more reasonable temperature (68) but it's back down to 60 so far. The killifish shelf is a much more stable temperature, though, with the heaters all working well and towels for insulation. Its holding at about 72.
So far, one ramshorn snail has appeared in my java moss. I'm keeping the moss in a big container and splitting it up between the fry. I haven't found any snails yet in the other plants, but haven't gotten a chance to move it over to my other tanks yet. This week school should be less chaotic, .

I'm glad some hatched. You might get more later, otherwise there is an excellent chance of getting a pair in the 3 you have. The cooler temps are not really a problem for most killies. Only rarely do my whitei tanks get as high as 72, I don't use heaters and the water gets down into the low 60 in the winter, yet they still breed. Gardneri are the same, cooler temps are ok with them too. Some killies need the cooler temps to do well, a few don't spawn unless the water is in a certain range, but the "easier" species like the ones you have are pretty tolerant. Daily fluctuations are also not much problems for killies, they generally are adapted to smaller bodies of water that don't home steady temps like the oceans or large rivers. In the wild, fish like whitei are found in shallow water where the temps likely fluctuate quite a from day to night.
The type of cover on the tanks affects the evaporation rate which can affect the temperature of the water a great deal. Tight covers make the water warmer, screen tops cool it down.
Also, most people like it warmer inside in the winter, you might actually find the room warmer once it gets cold outside.

I had four new whitei fry since I re-hydrated the peat! I moved the older fry to a bigger container, and I'm worried that I hurt one of them in the process (I poured them out of the betta cup they were previously in, and one got caught on the lip... I think I hit him with the eyedropper as I was trying to wash him out). He wasn't as active as the other two. But, even if he doesn't make it, I still have 6 healthy whitei fry and a biassa!
I'm sure that once the temperatures outside get cold enough that the building turns off the AC to all rooms, it will warm up in here. I'm glad my killies should be OK with the temperature fluctuations we do have, and THRILLED that 72 is plenty warm for them. The whitei are going to be on my desk once they get bigger (right now they're on the fish shelf wiht the others), and it could be more difficult to regulate temperature there. I'll have to wait and see, though... I'm sending my roommate to buy me glass this week I think, and I've already got a filter for it starting in my goldfish tank.
