  1. Default Black dot on dwarf gourami


    0 Not allowed!
    Hi everyone. New to The forum. I have a dwarf gourami in my 20 gallon tank. Its been in there for a good 6 months without issue. It recently developed a small black spot on one of its fins. Any ideas on what it could be or if it is even something to worry about? The fish doesn't appear to have any other problems.

    Many things can cause black spots. To start guessing, we need to know the ammonia, nitrite, and nitrate levels in the tank, other fish in the tank, and the size tank is the fish in.
    When I go fishing I just place a sharp rock in the water and sit there waiting for all the dead fish to float to the top... Kingfisher

    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
    Tolerance is a great thing to have, so is the ability to shut up.

    I can explain it to you, but I can't understand it for you.

    Can you give some examples? I hardly know any.

    Ok. Just ran the API test kit. Ammonia is at 0. Maybe the slightest touch of green, but not up to the .25 ppm level. Nitrite is at 0. Nitrate at 5-10 ppm I would say. It's orange, but pretty light. Pretty hard to tell on those color charts sometimes.

    It's a 20 gallon tall. Has a Penguin 150 filter for 30 gallons. Shares a home with 6 zebra danios and 7 tiger barbs. The gourami is the king of the tank. The barbs chase each other sometimes, but never mess with him.

    Could just be an age spot if the fish is very elderly, although if it came on suddenly I'd be concerned.

    More of a concern though is your stock list. Tiger barbs have no place in a 20gal tank. They become quite large barbs and need 55gal minimum. Can you upgrade the tank at all?

    your fish seems to otherwise be healthy, so I would consider the spot worth monitoring but not worth worrying.
    As mentioned, your gourami does not appear to be exhibiting any other signs of illness and the spot itself is a very vague
    thing as Mommy1 said.

    I guess I'd be relieved it was just an age spot. Much better than an infection or parasite. As for tank size, I wish id gotten at least a 30, but there were lots of people that said 20 is fine as a minimum tank size for a small group of tiger barbs. I did quite a bit of research when I was getting started.

    If you have a smartphone, tablet, laptop or PC, download the API color charts to your device. I store them in my photo gallery. Adjust your brightness to 100% and use your device to check your test results. Hold the test tube against the white of the chart. If you use this method it doesn't matter what your room light is. The color charts on the API website are very different and much easier to read than the one that comes with the test kit.

    Off the top of my head, ammonia, nitrite, and nitrate poisoning, internal and external parasites, injuries from other fish, heater burns. I'm sure there are more reasons but these are the ones I can remember quickly.

    I've also seen black spots (along with blood spots) in fish that have various infections and, more recently in one of my barbs dropsy.
