Its pretty hot outside but the air conditioner is on and the aquarium heaters are off. i have 2 really small five and six gallon aquariums that are around 82 degrees but my 30 gallon is at 78 degrees. i have fish in both small aquariums, should i be worried, and how can i lower the temperature?
I have one tetra in a 5 gallon and two glofish in a 6 gallon and a four and a half inch cihclid in the 30 gallon
82F is not too high you shouldn’t really worry.
many fish can survive in that temp. and actually like it.
but what you can do is open the hood so air can get in also do not turn on the lights and get a bigger air stone like those really long ones.
Open the hoods/lids and if you can increase the air flow in the tanks by adding more air bars, air stones. You can also remove some water and add cooler water to the tanks but your temp isn’t that high and I’d try opening the lids first.
82F? That’s actually not too hot. Most tropical fish actually thrive in a temperature range of 78 to 82F, so your fish might in fact be fine. I do not recommend keeping the heaters off because since the air conditioning is on, it could cause a fluctuation in water temperature which is going to be very stressful for your fish.
What fish are you keeping? In the two small 5 and 6g tanks, all you should have is one betta, in terms of fish, in each, and 82F is a perfect temperature for them. What about your 30g? If you’re keeping goldfish or minnows then the temperature should be between 68 and 74F because they are cold water species. It’s not easy to lower the temperature because of fluctuations which can kill sensitive fish, but I’m not even sure you need to do this if you’re not even caring for cold water species.
"I have one tetra in a 5 gallon and two glofish in a 6 gallon and a four and a half inch cihclid in the 30 gallon"
Tetras, danios are cichlids are tropical. Those temperatures are fine for them. However, their tanks are NOT. Tetras and danios are schooling fish! They must be kept in groups of at least six. A 5-6g tank is too small for one school of them, I highly recommend upgrading to a 15-20g and keeping one school. Your fish are going to get stressed from being kept alone and will die.
Open the covers/hoods on the tank, add more water movement through the use of airstones/powerheads, and turn off the lights. You could do a water change and put slightly colder water back in (make sure not to drop the temp. too much too fast). If the tanks are along exterior walls of the house especially if they are by windows I would recommend moving them since they are small tanks. If you can’t move them or they are receiving light from windows you should close the blinds/curtains. Move tank equipment like pumps, filters, etc. try to get them as far away from the tank as functionally possible or get as much airflow between then and the tank as you can.
82 is not to bad, Though I wish you had said what kind of fish they were, hot water holds less oxygen, you may need to add more circulation with an airstone, but the only fish that should be in a tank that small are bettas, bettas have a labrynth organ that lets them breath oxygen straight from the air because they are from places were the water gets really hot, even over 82 degrees, and does not always have sufficiant oxygen for them. 82 degrees is a perfectly fine temp for them. but other tropicals may need more oxygen, if you cant get more circulation, use a cup to scoop tank water out, and pour it back in to create bubles, this will temporaroly airate the water, you will have to do this as often as possible.
leave the heaters on, they will shut on and off to regulate the temperature, if it is too hot, it will shut off, but if you leave it off, the tempurature could drop suddenly in the night and your fish could suffer from shock.
