Hello all, I have read quite a few thread about how the pygos can handle cold temperature as low as 57f.
I just wanted to point out, my fish tank is in the garage right now .the past few days been freezing cold and the water temperature is at about 57.5 F for 3 days already, my Rhom is still swimming around like normal, does not seem stress out at all.
Anyone experienced something similar?
 
57 fahrenheit is pretty low, and i would think that you will feel the consequences soon.
However... Piranhas are pretty tough, and can survive where others would die.
I actually once did a huge mistake! It's a few years ago, when i filled my new aquarium, which had a cycled filter. But i just filled it with water, and then of course, the water is damn cold. I forgot that and i added my piranhas. I would think it was even lower than your current tempereture. But they survived, and apparently was not harmed at all.

you figure were rhoms come from rarely sees anything under 80 degrees so why wouldn't you be heating the tank? 57ish is the temperature my natives start to slow down, I can't imagine what its doing to your rhom's system right now.

They start slowing down in low 70s. I had a power outage several years ago for several weeks and the consensus was to try and keep the tank above.

You will slowly kill him at that temp.
 
57ish seems pretty cold although I haven't tried I know my piranhas (rhom, manueli, rbp) have survived in the mid 60s during water changes in the winter. They seemed to slow down a lot but had no problems for the most part. I recently lost 3x channa micropeltes that was in my pond but was too hard net out for the winter at 50 degrees continuous. It actually dipped much lower than that in spikes of one or two days but what ended up killing them was long term under 55degrees. They were about 20-24"
 
U can raise the temp in his tank by adding a bucket of warm water every half hour,if u do this daily several times a day u can keep him in there(I've done this with other tropical before)
