I have some discus that are kept at 82F-84F. Was wondering if there are any Corys that would live comfortably in that temperature. I see on the profile section some have a range of up to 80.6F, some are 78.8F. If this means that Corys are out of the question, I'd appreciate ideas on other mild-mannered schooling catfish that would enjoy that temperature, pH of around 6.8. Thanks!

I know Discus people who keep sterbai at high temperatures. Long term I am not sure what effect the high temp. has on their well being.

Jimmy,
You should be fine with any Corydoras sp. naturally found alongside Discus. I would suggest any of the upper Rio Negro corys (C. adolfoi, C. burgessi, C. davidsandsi, C. imitator, et al) or upper Orinoco corys (C. delphax, C. ostecarus, etc). Just stay away from the llanos spp. and those from the upper Peruvian Amazon or Rio Napo areas.

Corydoras Sterbai are OK up to 24'C/75'F to 28'C/82'F according to the Cat-eLog. Slightly higher is probably not a great problem, but obviously if you start going noticably above 30'C/86'F, I would think that their life-expectancy starts going downhill quite quickly.

Aeneus and Paleatus seem to breathe more quickly and show signs of distress past 78 degrees F. Trilineatus seem to enjoy the water around 75-76 degrees F. Just an observation.

I keep Corydoras sterbai, Corydoras aeneus and Albino (either Sterbi or Bronze Albino, im not sure) with my discus, all @ 28-29*C (82.4-84.2*F), I also have 25 glowlight tetras (suggested temps 22-26*C) and all fish are doing great, all grow exceptionally well, especially a gibby I have in there.

When I first got the discus, I kept them @ 32*C (89.6*F) to help them settle and get their appetites up, when I added 2 sterbi to the tank 1 died for no apparent reason, I put this down to the temperature, so over the next week I dropped the temps to 28*C, then I stocked up on the corys I have now, 14 in total, all health and doing a great job of keeping the sand clean in my 450 litre display tank. Nice!

The most suitable species for temperatures in the mid eighties F. in my opinion would be C. gossei and C. seussi, as well as those mentioned by Shane.

I was able to get 3 Sterbai for my tank. One is obviously larger than the other two, so I'm not sure if I can draw conclusions yet. Their coloration is awesome, the pattern is so sharp and crisp, quickly becoming my favorite of all the Cory varieties!! They are active, spending time swimming about together.

Hi all,

I am searching for a suitable Cory for a discus tank, and found this thread. I am wondering if any have found more types that do well at higher temps. Temp in my tank will typically be 82F but may go higher depending on situation. Also, would Jullii's or Schwartzi's do well or do they need lower temps. Thanks,

Adrian

HI,condor,
i would not think that high a temperature are suitable for the julii & schwartzi,as these cory are mostly suitable for temperature between 75F to 78F.if they are expose to temperature higher than 82F for long term ,they simply would become stress and they will perish.but i think you should stick to the recommendation from that of ian,shane and matsp.i would in my opinion get a group of sterbai,as they are a stunning looking corys and a group of sterbai will surely make yours discus tank look stunning.
good luck with your search for your discus tank.

Thank you corybrummie2010, I appreciate the input. I agree, sterbai are definitely good looking fish.

same thing for me, looking for a group of corries for my discus tank. what about bronze corries?

Not really good at higher temps. Most corys live in smaller rivers that flow in shaded areas, and they don't really get that warm. There are several suggestions in the posts above that are good, and at least some of those shouldn't be very difficult to find.

Agreed on the recommendations from Shane, as well as the advisement to refrain from subjecting aeneus and paleatus to sustained temps. beyond the mid 70's F. Mine do best on the cooler end of the recommended temperature range. My adolfois and sterbais both tolerate warmer water much more readily but I do not keep discus so the warmest I've had them is 82, and they've both been comfortable enough to breed at that temp.
