Can a Betta do ok at 84 degrees?

[jadaBlu]

My new betta Nano seems happy and content he has already built a bubble nest after only 2 days of having him. I have him in a 5 gallon tank with flat heater that heats the tank up just a little more. He's in a bathrooms which has a heating vent so the bathroom stays warm. The door is shut for now because I need to get a hood and my cat is noticing him. I just checked the temperature and it runs about 84 degrees. Is 84 degrees going to be ok?

Oh my... more than 82 degrees is not okay. try turning it down a bit or else your betta'll burn xD

The betta won't "burn" lol, but he can overheat. Try to get it down to 82, close your cat in a room and open the bathroom door to let the air circulate.

I know. that's what i mean't by "burn"

Bettas can get heater burn from pressing against the heater. I hope you can get the temp down. :)

.84 is actually fine. Bettas can be kept between 76-86 degrees. At 84 he will rarely get sick and be active, but he will be better off at 82

oops. (bad memory sometimes) isnt 86 too... hot?

I agree, 84, up to 86 is really fine for most betta fish. I have kept a few betta fish at this temp. Keep in mind a few factors though: the heat will cause your fish to have a faster/higher metabolism, and as such should be fed just a little more (don't overdo it!), and as such will pollute the water more, and as such should have one more water change per week (50%).
Also, long term at this temp will shorten the lifespan for the above mentioned increased metabolism. By how much? Hard to say. If your betta was going to live 7 years, maybe now it will only live 6 years. Maybe the higher temp will ward off an ich infection because you let the water go to long and he will then be able to live longer because of it! Plus you figure some flux in temp is normal was well, just make sure they are not fast/dramatic changes. That is when the fish have problems!

Short term this is fine. Long term, he will live a shorter lifespan because his metabolism will be so sped up.

I kept the box and the receept for the heater I will clean it an return it and get heater where I have more control over the temperature.
