I have an 8 inch oscar in a 55 gallon tank, i recently had to move him to a smaller tank for a short period of time. He was unhappy, swimming around frantically, running into walls, so I put him back into his home. Water conditions are all good, but he is laying on the bottom of the tank and is missing scales, he also has no interest in eating...please help!! I dont want to lose Fred!

    Oscars will get a bit of an attitude and pot from moving them around.  The change can be extremely stressful to these fish.  They normally come around.  I would try some of his favorite food or maybe some live foods to perk it up a bit.

    Sounds like you have neon tetra disease for which there is no known cure :( Most say to get them out as fast as you can to try and save the ones you can. If they start to feed on them they will all die. I had a whole tank lost, but a few when I went to a local Pet Store and it was passed to my fish of Many,many years! I was heartbroken:( Clean you tank well.Good luck.

    Check your amonia levels.  High amonia will tend to make fish itchy.

    I included the article on Fish Disease and Treatment. It might be Fin & Tail rot which is a bacteial infection. He could have had it when you brought him home. He could have hurt himself somehow in the tank and it caused a bacterial infection. Another fish could have nipped him. It happens. Anyway, look at the article and find the symptoms and check out that disease and just look at symptoms in general. The recomended treatment is there.

    My freshwater fish a black one got suddenly weak when I changed the water. After a while, his tail and his fins got torn. I took him into another tank and he's now a little bit active. The water problem's solved but he seems to be struggleing and it seems also that his tail is weighing him down. One problem after another (sigh) Ripped tail and heavy tail .....:S

      With the eyes starting to bulge, that could be pop eye and is thought to be the result of poor nutrition. It's a bacterial infection, and may also be what's causing their mouth to rot. Bacterial infection can be treated successfully with fish medications that contain a form of penicillin or amoxicillin, sometimes other bacterial fish medications will work too.

    In my tank is two beautiful Jack Dempseys, unfortunately i started to notice that the smallest one is not moving around so much anymore and the eyes looks like it wants to pop out. Added recently three Malawi's to the tank. Please help.

      There are many things that can cause that.  Could be from a fight, bacterial infection, poor water conditions.  Check your water levels would be the first place to start.

    How do I tell the difference in the type of disease? My albino clownknife just got things on him that look like oversized paracites and they are only on him?

      Not sure what your fish has, but some of the most common diseases are either Ich (which is a parasite that looks like somebody sprinkled the fish with salt) or a fungal infection (which can look like little cottony patches). A larger parasite could be Argulus, or fish lice. I'm glad you are only seeing these things on one fish, but if it is a parasite, or any other disease, it can spread.

      See if you can't narrow down what the problem is. Look at your fish very closely. then check the information on the page above again. The chart near the top of this page gives a quick look at the types of symptoms (what to look for) and what that diseases is. The detailed information for each disease, which is further down the page, describes the symptoms in more depth as well as treatments. Good luck!

    Hello I have a 60Lt tank, 5 pristella maxillaris, 15 (began with a couple) apistogramma agassizi, 3 corydoras (dwarf maybe?). The problem is one of the apistos has become shy, pale and secluded under a rock, I don't think it's eating a lot. No other symptoms I can describe. The other problem is with one of the pristellas, it also is pale, and has a strange redness and maybe swelling on the bottom half of the tail fin. It is swimming as if it has a weight on the tail fin, so it swims with an angle (head up, tail down). Two days ago my apple snail died, don't know if this is related. Thanks for any feedback.

      Check your amonia levels.  Amonia will tend to make the fish turn pale.
