    Just looking through the earlier portions of the thread and I noticed some mention about keeping the substrate or even bare bottom healthy. How can this be achieved?

    Intending to add a group of C sterbai to a metre square pond, which is currently bare bottom.

    Re: Corydoras Keepers

    My guess...

    [1] C. atropersonatus (colors somewhat pale)
    [2] C. robineae
    [3] C. aeneus ????
    [4] ??? doubt if it's agassizii
    [5] C. aeneus ???? still doesn't look like a concolor ley...
    [6] juvenile C. napoensis???

    Perhaps other more knowledgeable members can chip in.

    Hmm. Looking at 3 & 5 again, it does seem like C. Concolor is wrong. Their coloration should be more even across the body..

    Rounded substrates are better, if not sand. A bare bottom tank does not allow the Corydoras to express their natural habit of sifting through the sand to search for food.

    A pond was mentioned. What kind of pond? Mud bottom? Rough? Tiled? A rough bottom would erode the barbels of Corydoras.

    Re: Corydoras Keepers

    Wouldn't go so far as to call it rough. In a sense it is just a large container. Either way it seems that the bacteria formed on bare bottoms cannot be regularly eliminated, so I will have to use sand anyway.

    Re: Corydoras Keepers

    No.1 is not atropersonatus. It is something close to C. kanei.
    No.2 is definitely a robineae with stress coloration.
    No.3 and 5 are the same, and probably one of the C-numbers close to the C. elegans/napoensis group.
    No.4 is a saddlenose-type Corydoras. Possibly a C-number close to Corydoras vittatus.
    No.6 is probably CW044. This is just my guess, it could be something else.

    A thin layer of sand would be best for most Corydoras. In the wild they live over all sorts of substrates, even on rough rocky stream beds, as evidenced by several videos on Youtube. It is not so much about the substrate, but rather about the bacteria that live in the substrate. If the Corydoras are in bad health, they will pick up all sorts of bugs from a detritus-filled substrate.

    I found that though they have big round eyes, they do not appear to be able to see anything except light. Maybe they are able to see well at night. When they are fed during the day, it appears that they are blindly groping their way around to feel (smell?) the food rather than going straight for it. They spend most of their time parking at the bottom because they can't see where they are. Though they are really cute, this kind of behaviour does not appeal to me, so I stopped keeping them.

    I used a bare bottom tank (without substrate), as I wanted to give them a good life rather than let them rummage in the rough sand and hurt their tender whiskers. There's really no need to 'exercise' their barbels, since this is what domestication is - they will adapt nicely to their new 'lifestyle' in time.

    Among all Corys, I find Sterbais are best as simple adorable pets because they are relatively low cost, and also do not have markings or dark colour bands that conceal their eyes. Their bright yellow 'hands' are also an attractive feature. But advanced Cory keepers will prefer more fancy breeds.

    Re: Corydoras Keepers

    How aware are Singapore's LFS owners about corydoras secretions under stressful packaging?

    Re: Corydoras Keepers

    Best answer is probably go to LFS operators who understand Corydoras!!

    They knowing, isn't the biggest deal. You knowing, is what make things count!

    Re: Corydoras Keepers

    That's a real pity, wanted to pick some corydoras up at the farms in the east; but it looks like I'll pay a little more and pick them up from the nearby fish store instead. How do you guys transport your cories?

    Re: Corydoras Keepers

    I actually think most LFS pack similarly. Only a handful use higher quality packaging. Even then, that does not address the secretion due to stress. You'll probably need a huge bag/pail with a lot more water if that's of concern.

    A tip for beginners:
    When you buy Corys, or any fish for that matter, go straight home immediately after buying. Never never go window shopping with the bag of fish in hand or in your handbag.

    When you reach home, never never pour the fish into your tank straight away. They may look fine and swim fine, but they can never show their internal suffering or internal damage on their faces for you to see their suffering. Always place the whole plastic bag of fish into your fish tank and let it float there for about 20 minutes. This is to equalise the water temperature in the bag. Fold the bag's top nicely down (like how guys fold up their long sleeves to their elbow). This will make the open bag float beautifully on the water. After that, with the bag still floating in the tank, replace half the bag's water with the tank water and wait for another 20 minutes. Do not pour the replaced water into your tank. Discard it. You can then transfer the fish to your tank with a soft fish net. Again, discard the bag's water.

    This is only a recommended routine but your fish's health also depends on the water condition of your tank. If that is not good, the fish will also suffer. That is why it is best to first gain experience with low-cost fish before embarking having a go at costly fish like arowana, discus, goldfish, luohan, etc.

    Re: Corydoras Keepers

    Every day, at least once. Do not miss feeding them. Best to drop in a sinking tablet or two, after lights are out, if they are in a community tank. My Corydoras get Tetrabits every day. If it's just 6 sterbai, 1 Viformo tablet or 1 Sera O-Nip tab should do the trick. Give them frozen bloodworm as a treat from time to time, or Hikari Carnivore Pellets.

    Re: Corydoras Keepers

    I'm using hikari carnivore pellets now. They appear to have some difficulty finding in a metre square pond. I leave it in the area with sand. Typically I leave about 6-7 of those pellets in there, but I haven't observed them eating. There are also two bristle noses and one Ropefish in there, which I believe is some competition.
