When is hot too hot?

Summer in Japan has arrived and it's hot!
And my tanks have hit 30 degrees Celsius!

I'm keeping an ery ery and a baby rohm and while I'm not panicking yet, I'm wondering how high a temperature they can tolerate for a couple of months?

I have made sure that there's more oxygen in the water and I'll be buying some fans to help with evaporating thus lowering the temperature.

Might be worth it for you to get a chiller.

Really depends on the size in question as well... i mean personally i'm not familiar with those fish, but living in Asia as well, i'm used to dealing with very warm water...

I personally run a chiller on my planted tank coz most plants do not do well at all under those temps, but as far as fish go, running my A/C helps bring temps down a bit, a fan will maybe bring temp down by a further 1-2'C max, so dont expect miracles from that...

You can aso consider freezing bottles of ice water and floating them in your tank to bring down temps, but will also require a lot of re-freezing and replacing bottles that arent cold anymore...

Yeah, I thought about getting a chiller for each tank, but it's a bit expensive.


Fans won't lower the temp all that much I know, but even a couple of degrees would help.

The ice bottle trick works, but I'm not home during the day, so the effect would be brief and the temperature fluctuations would probably be worse for the fish

Yeah, the ice bottles only work if someone is home and willing to switch them out at regular intervals...

Honestly, at least for me the only two ways i've been able to control tank temps in hot asian summers is either chillers or cooler ambient room temps...

Sadly there just doesnt seem to be a cheap way to keep temps down for extended periods of time that i have found...

The wolf and piranha are native to the Amazon which stays pretty steady at 30 C, so they should be fine. The betta has been reported to survive long periods in much warmer water (35 C), so it should be fine.

However, we don't know the size of your tanks, the oxygen, ammonia, nitrites or nitrate levels, or the health of your fish. Temperature can kill fish if other parameters are off, since it reduces oxygen, and makes many items more deadly. And small tanks can become lethal very quickly.

I'd reduce feeding, keep on adding aeration, and make sure to keep the tank water in great condition.
