Do you think that Buenos Aires Tetra's, Guppy's & Peppered Corydoras survive in a 16 deg. temperature?.

I guess the other day they will turn to ice cubes NOOOOOOOOOOOOOOOOOO.

Guppies might be okay but I think it would be too cool for the cories and BA tetras.

Why do you ask? (curious)

Before you criticize someone walk a mile in their shoes. That way you're a mile away and you have their shoes.

I'm guessing that's in celcius or you'd have fishy popsicles. I can't get the temp calc on this site to work(broken?) but that's 60.8F. The guppies would probably be ok as well as the peppered cories but I'm not sure about the tetras. They can withstand a wide temp range but the profiles here says 68F minimum preferred and a few other sites say 70-72.

i would stick to temps around upper 70's to early 80's. i've never had a tank go below 72, so im not sure on how cold before the lil guys freeze..

I'd consider the guppies to be the least likely to survive. Guppies are natives of places such as Trinidad, which is strictly tropical if I recal correctly. Guppies tend to like their water fairly warm. Domestic strains are likely to be even less happy below around 22°C.

Buenos Aires Tetras are fairly tough fishes, but I'm not sure if that extends to living in waters below 21°C. However, a distribution check should assist here - if the species is sympatric with the Bloodfin, Aphyocharax rubropinnis, then it should be capable of surviving in water that is cooler than the 'normal' tropical aquarium range. Bloodfins collected from the wild are capable of surviving temperatures as low as 10°C, which occur periodically in their native waters. So if there are any Buenos Aires Tetras sharing the same waters, then those too should be capable of surviving cooler temperatures. Whether aquarium bred specimens would do so, however, is a moot point.

Peppered Corys might go down to 16°C for relatively short periods, but it's again debatable whether they would survive those temperatures for an extended time. Domesticated ones tend to be bred in warmer waters. However, given that quite a few Corydoras experience temperature drops in the wild, and that these (combined with an influx of oxygenated rainwater) act as a spawning stimulus, it's possible that the Peppered Corys could survive 16°C. Before committing yourself to an experiment, however, make sure you have facilities handy to hospitalise them and warm them up again if the experiment proves to be a failure!

One Corydoras species that WILL live at 16°C for fairly extended periods is - wait for it - the Panda Cory. I've had fry live at 16°C for days at a time during cold spells when I used a nursery aquarium in my unheated kitchen to raise them. They'll live at 19°C more or less indefinitely, and I suspect that they may even survive a temperature drop as low as 12°C for a limited period. However, Panda Corys are natives of streams and rivers that are fed by Andean meltwaters, and are thus naturally adapted to the cooler end of the 'tropical' temperature scale, and react badly to being overheated.
