Water Temperature

I have kept platies in a tank that ranges between 80-84 (on a really hot day)
I keep the room air conditioned, but at the top of my house, there isn't much I can do to help it....

They do great, and have even fought off the initial stress diseases from when I first got them (Mail had culminaris and fin rot, and a female, purchased separately had ick. (sneaky ich...)
 
forgot to mention this earlier... but i also have a DP in the tank thats 82F and hes doing great.

Although most would argue that they are not community fish, i've never had problems.
 
I've had a couple Dwarf puffers in a community tank at 80-82 degrees since May and havent had any problems. Puffers are prolly the least aggressive fish in the tank, but prob have the most personality.

2 Dwarf Puffers
1 Dwarf Gourami
2 Cheery Barbs
3 Spotted Corys
2 German Blue Rams
1 Spotted Climbing Perch
1 Bumble Bee Catfish
 
my 36g is kept around 80-82 and I have neons, cardinals, and brochis.....and a mystery snail-the higher temps increase the mystery snails growth which will shorten its life span. All have been healthy and well, the neons for over a year now.
 
Suprised no-one's mentioned Gourami's...or Rainbowfish. The latter are very hardy, have to endure extreme fluctuations in temperature and salinity.

My tank rarely gets below 80, and is heated by the ambient temperature of my flat - typically sitting at 82. It does cool down a degree or 2 at night-time too (replicating nature imo). Fish that seem to thrive are my swordtails and CA cichlids suprisingly. Tetra's didn't like it much.

Many discus keepers do keep cardinals (over neons, since they say the cardinals tolerate the higher temps) with corydoras sterbai (again, tolerate higer temps). As stated earlier, Rams do well too.

If your acclimitisation technique is slow and gentle, with a stable tank, I think most captive bred fish should be able to live in these conditions. Their metabolism will increase and lifespan possibly shorten slightly due to the slightly raised temperature.

Just look at what commercial breeders do to their stock, particularly Asain! Like raising neons in 90 degree water with hormones etc!
 
Over 80 degrees is too warm for rainbowfish on a regular basis (at least the adults). Mid seventies is ideal, they'll be less likely to come down with columnaris or any other stress-related disease, and show more breeding behavior (always a good sign).

Cardinals actually do thrive well in high temperatures. Neons, however, seem to die or so at least in my experience when temp is increased.

I'm an Asian yet I never see nor heard from anyone able to keep neons in 90 degrees.:headshake2:

:iagree:
 
I keep my community tank at 84*F and I have Neon Tetras, all are doing well. Of course I am assuming my digital thermo. is accurate.
 
I have fancy guppies in 25-gallon containers outside (to keep mosquitos from breeding in my floating plants). They are doing fine, and daytime temps here often are up into the 90s.
