Suggested Warmer Temperature Fish

[Tank Voyeur]

Fish Friends,

I just moved into a new rental house for past two weeks, and am just about ready to set up a new 5 gallon nano type tank. However, we don't have air conditioning and the temperature within the house can easily reach as high as 85-90F.

I was originally going to set up plants.....and then add sparkling gouramis, crayfish, and perhaps a few snails. However, the temperature within the house is giving me pause to reconsider.

Given its a 5 gallon with less room for error, can you suggest options for fish that could better thrive if the temperature consistently reaches up to 85-90 during these current summer days? (....and thats before I entertain any type of chiller mechanism or fan)

If you can't upgrade to a 10 gallon, Green Neon Tetras may work. They're smaller than regular Neons and reportedly will tolerate temps into the mid-80s or higher. A half dozen may work for you.

If the tank is out of the sun then I don't think the tank will get hotter than the air temp and there are many fish that will work in that temp range. However I don't recommend many fish in a tank that small. Not a fan of nano tank thing myself.

Yeah, I agree with this. In your case, a larger tank would have the benefit of not heating up as quickly. If you can swing it, a 15 gallon would give you a ton more flexibility with regard to water temp, species, and stable water parameters. Even a 10 gallon is way better than a 5 gallon.

If your tank gets direct sunlight, throw a heavy towel over it during that part of the day.

A 5 gal is a good size for a betta and that temperature will be fine the water won't be a hot as the air.

Thank you all for the input!

I already bought the 5 gallon (Fluval Spec V, still in the box) which I could take back, but I also bought a stand which I assembled.....so I'm sticking with the 5.
This is a challenge, as I've previously had a 60 gallon.

Green tetras sound feasible....and I've read that Red Cherry Shrimp can withstand extremes.....

However, I'm also going to try my hand at a DIY cooling fan to blow across the surface.

....if only there were such a species as a Dwarf Discus.....

I don't believe any dwarf cichlid can go in a 5 gallon even the smallest shell dwellers. You could also look at ember tetras their ideal parameters are 73-84 degrees. And smaller than most tetras. Freshwater shrimp have become one of my favourite things to watch in my community tank tbh. Their energetic behaviour makes them a centre piece.

I vote shrimp all the way! I've got some and they've survived everything my inexperienced self has done to this poor tank.

One last question (yeah, right).....

Will a dwarf crayfish be able to handle occasional high temps? .....any more or less so than the fish?
