    Default Cory's not such a good idea?

    Hi everyone

    Just wanted to ask if anyone experiences trouble with Cory's? They're an awesome fish, especially in large numbers, but I have doubts about their ability to go the distance in 82/84f temps.

    If anyone's had problems with them then please let me know. I'm new to discus, so don't want sickly tank mates in my first attempt.

    Thanks, Rob

    I've had sterbais in a couple tanks at 84 for almost a year. So far no problems.

    Same here, Sterbais are a good choice in discus tanks.

    Interestingly.....I have had three Green Corys in my 86 degree 75g tank for three months and they're doing great. Hope they continue doing well as they are a joy to watch and really help keep the bottom cleaner of not eaten food. In my 55g tank, I have four Corys of three species (green, sterbai, and Julia) at 82 degrees all doing fine.

    C. aeneus will live through anything. Sterbais, juliis, axelrodi, etc. will all do fine. Trilineatus and paleatus will not make it. Adult pandas can handle the heat, but juveniles cannot. Get at least a dozen and they'll look awesome.

    What about Albino, Panda, Pepper & Adolfoi Cory?

    Have some Albino and plan to get a pair or two of the other 3. Which can stand temps of 82 and which won't make it?

    Albinos and adolfois work. You will get losses with panda as younger fish cannot handle the heat. I've been able to keep pandas by raising the temperatures gradually from 75F to 82F. I assume the peppers are paleatus and those require cooler temps.

    Cories will behave completely differently in a school. I recommend a minimum of six. I keep two dozen sterbais in a 110 Gal and they're a blast.

    Pandas and paleatus would really rather not be at discus temps. They survive, but even aeneus would be a better choice. Adolfoi do very well at discus temps. As others have said, sterbai are the best choice but adolfoi and duplicareus aren't far behind.

    Hypancistrus like L201 are a great if you don't feed beefheart. You won't see them out and about like cories, but they eat way more than cories when the lights are off.

    I have sterbai with my discus for a long time that I bought from Martha Morris and no problems.
    She might have some for sale now.

    Thanks again guys. Yet more information to follow up on. I'm planning at least 10 cory's. Maybe more, after what you've said Willie. I just started up a journal for my first discus tank. Please do chime in with advice along the way. The excitement is almost unbearable, and I don't want that to cause mistakes.... Rob

    I have 8 of 3-4" discus in 150g.

    Corys in the same tank = 10 sterbai, 3 albino, 3 pepper (paleatus, 2 common 1 long fin), 2 similis.
    Water temp = 84-86F (29-30C)

    They are doing great, even the peppers. (note: I'm living in the tropic where room temp is 28-34C anyway,
    so our local bred fish might be high temp tolerant than other countries)

    My 10 sterbai were even having fun throwing xxx party (excuse my language) now and then,
    but I have never seen any young fry though. (might be too challenging as a fry to survive
    with these guys swimming around searching for food all day)

    The thing about keeping cory is, I have to put a thin layer of sand substrate,
    which some discus pros might not like it.

    Also, beside of my affection to Corys, my first idea of having them in discus tank was that
    I wanted them to somewhat clean the bottom of the tank (typical idea, I guess).
    But then I ended up finding out that, not only some of my discus are so picky/finicky eaters
    that will wait for quite a while before his/her majesty would start eating,
    while most of them were busy chasing each other around during feeding time to protect "their food".

    Then guess who ended up enjoying the feast during those time?
    Ask my fat as a pig corys.

    I've bred and raised many sterbai cories, all in bare bottom tanks. I stopped raising them because there wasn't much of a market for them. Hey Jay.
