    Do you guys have this problem of fungus growth on your cories especially pandas? They would seem to struggle to breath at the last stages by dashing the surface for air at increasing frequency. The pandas nowaday are quite bad.

    none whatsoever
    go and test your water, i suspect you have high nitrates or high COD
    either way, do water changes, add some salt (predissolved, and add slowly)
    the fungus is a sign that the fish are suffering due to poor water conditions

    DEA, sorry but whats COD? I heard that cories are very sensitive to salt and medications, is that true?

    BTW do you guys feed ur cories with LIVE tubifex? I kind of think they are high risk food. But they bring about tremendous growth. I was in a LFS and they have this whole batch of baby pandas eating tubifex worms.

    rain, do ur cories do that very often even when the water is well aerated? Do they do that for fun or are they like bettas?

    COD = chemical oxygen demand, a measure of how 'polluted' your tank is with organic substances

    cories in general aren't sensitive to salt, but in particular pandas have been known to die on contact with salt streams
    thus, mix any salt carefully with the tank water

    cories gulp air only when the water is low on oxygen
    mine just sit on the bottom looking like statues

    no my pandas do not gulp air from surface often. its more like when they swim and suddenly bump into another cory, they shot right up to the surface. perhaps they can a gulp of air along the way too.

    im not sure if pandas r so weak, but if so could be due to in breeding i guess.

    hope ur corydoras will be fine soon

    ps: i never feed tubi cos they r very dirty. mine eat blood worms and at times they dont mind pellets too.

    Another qns. Do cories barbels grow back after that had been damaged? I noticed lots of cories in LFS have damaged barbels.

    What is the scientific name of the common spotted cory in LFS? I noticed there are quite a number of cories that looks like the spotted cory. Thanks

    yes, evidently they do grow back, given good conditions

    spotted? you mean the marble or the leopard?
    leopard = trilineatus, marble = paleatus

    I've Albino, Panda, Bandits and Trilineatus in my 2ft tank.

    When food is given, the Albinos will start eating and eating and eating till they're satisfied.

    The Pandas will come along and try to push the Albinos aside, while getting at the food (Novotab, mainly).

    Then come the Trilineatus.

    Then, when the humans are miles away, come the Bandits.

    But the minute the Bandits sense a human's presence, they'll swim back to their hiding place (back of the tank, blocked by a big Java Fern on wood). Most of the time, the Trilineatus will follow them...

    You can guess which ones are nice and slim, while which are fat![]


    As to the frequency of going to the water surface for air, all except the Bandits do that once in awhile. I don't think it's the water condition in this case, though. I think they do that just for fun, sometimes...

    I LOVE CORYDORAS!

    simon, ever thought of teaching them to "freeze!"? lol! i tried taking pictures of my bettas before - gave up!

    foxemty, i don't think cories are nocturnal fish. they can be fed when the lights are on, but i think a few shy ones may only come out when the lights are off.
