That's awesome! Let's hope they live so you can compare them to some standard neos!
They're just plain ol' Neos that spent a few months outdoors. I think their size can be attributed to cool temps and tons of food. Trying to warm them up ever so slowly to acclimate them to indoor temps now.
I know someone locally to me.... she has 3 or 4 indoor aquariums and two outside "ponds" (aka half whiskey barrel style ponds). One she likes to keep shrimp and guppies in. She puts heaters in them during the winter and takes the heaters out during the warmer months. Last year, she took the heater out too early and we had a cold snap one night.... almost all the fish had died. Literally less than a handful left.... and the shrimp? Still shrimping around!
Yeah, I've lost a lot of shrimp to warm water but never to cold. And I've let them get awfully cold.
Well, it was getting just below zero last night and I tried to get well into this pond and bring in anything I could save in the last hours of daylight. It's not looking promising, very few white cloud fry to be found. I really hope they are just laying low and dormant because the water surface shimmered with them a couple of weeks ago. I'll be gutted if they are all gone. But I've messed with white clouds for a while now, and if anything comes back in droves it's Tan's fish. But from just swinging a net around I got more full grown sized fish than fry. And only got 7 whole shrimp out of digging through pounds of leaf litter and sludge with my fingers. Small ones I just let go back in the pond rather than foul up the buckets getting them into the clean water.
Out of fear of them freezing I took a 300W aquarium heater out of storage and set it as low as it goes and dropped it in for the night. Outdoors on a pond probably pushing 1,000 gallons and that was at about 44 F in temperature at the time. But there was a warm (well, not freezing) area for them to congregate last night. I don't care if it kills my heater, I just don't want to do the wrong thing for the living fauna. This pond steamed lightly when I went out yesterday morning without
a heater but the pond is deep enough (36") to get some ground warmth.
I found a few more shrimp today in the warm zone and they are whoppers. Makes me want to consider a much more leaf heavy approach and worry less about pristine water.
