    I am guessing it is a clownfish you just got, and it sounds stressed. That can happen with someclownfish, usually wild caught and it is usually dependent upon what type of condiitons they experience prior to reaching an aquarists tank. The first thing to do is check the water parameters, make sure the water is pristine. You may also want to add some rock or a large shell, so the fish has some hiding places. Then keep an eye on it since stress can cause illness.

I have 2 Elegator like fish. Got them day before and today observed both have some disease in eye. One side eye of both the fishes have got some opaque membrane and eyes are popping. Please advise what treatment can be given.

    It sounds like they could be infected with ich, have pop-eye, or some other type of eye problem. Try treating with penicillin or amoxicillin first. Also make sure you are feeding your fish the right foods to ensure they are receiving optimum nutrition.

I have a 10 gallon tank which has an elephant nose fish, a pleco, a tetra and a black marble angelfish in it. I recently moved from Maryland to Florida and the day after the move my angelfish lost interest in the flake food and the bloodworms and now it has developed white fuzz which is growing around its tail fin. Also some of its scales are turning white and it's other fins are becoming fuzzy as well. I was wondering what could be affecting my fish and how to treat it?!

    It sounds like you have a fungal disease, and yes, it could be affecting your fish. They are probably stressing from the move, but also the tank is really too small for these types of fish. To treat it, you are on the right page! Just go up to the section above called 'Fungal Diseases' and see the description of the symptoms of Fungus,  and how to it:)

I keep the electric yellow Neo in my 53-litre tank solely who has arrived a month or so ago. He has been adapting to the environment well (learned to ask for food by splashing the water within a week). After the death of Chanelle who is of the same species, the tank has been cleared, cleaned, dried and then exposed to direct sunlight for three weeks before his introduction. Currently, the tank bottom is not lined but there are several hiding places. Yesterday morning I noticed that Neo spits his food out after taking them in. His teeth turned darker red. His slime layer got peeled off at many points over his exterior (all on the head and body except one on the fail fin) (the white falloffs are 1.5mm across and 2cm apart on average) with the backward body worse. His back fin has a red base. He also raced through the tank and glanced off the glass bottom and sides is response to the supposed itch but improved today that he only circles quickly for several seconds when touched. In addition, Neo changed his sleeping location (where he finds most comfort, like home) from the rock cave to the corner below the filter inlet. During the day, he shows unusual interest in the filter outlet that he tries to swim up the down-pouring water. He also behaved like Chanelle, swimming in a shape of the number 8 against the tank front when idle, and approaches the TV next to the tank when it is switched on. He took a nap this afternoon for 1 hour 13 minutes which is not supposed to happen under daylight on a fish.

Hi, all of my goldfish have contracted fish lice though I have no idea from where. I change water, add medicines and ammonia level and nitrate level are minimum. I am totally shocked at this sudden infestation. As per advice I would add potassium permanganate to the whole tank. But for how many days do I have to continue this treatment? I discovered these pests attached to many of my fishes and have manually pulled out using tweezers. And I have added 3 teaspoons full of rock salt. Then I searched and found the cure. But for how many days do I need to continue this potassium permanganate therapy? I am really confused. Please answer me ASAP. Thanks in advance to anyone who helps.

    How long have you been doing it so far? Do it once and see how much it helps. Then do a regular water change and repeat the process. I would guess you would want to do this every day until you see it helping. And change a small amount of the water after every treatment.
  • ananya - 2013-08-05
    I did this treatment for three days. After the second day there were no visible signs of lice or eggs on their bodies or in the aquarium. The fishes are again acting normally, eating well (they had stopped eating due to infestation). Today it will be fourth day. Is there any chance of another outbreak if I stop the treatment after today? The treatment has an outstanding affect in curing the lice infestation. Thank you very much!

I have two silver angels. There is no change in their behaviour or apetite. Their appearance has also not changed. It's been two months now, suddenly both of them are showing red marks near mouth and fins. These marks are growing day by day. Are they diseased? If so what should I do? Suggest asap.

    Red streaks are a classic symptom of a bacterial infection. Usually the best way to get rid of this is by treating the water/fish with antibiotics. These include Tetracycline, Penicillin, Acriflavine, or Chloromycetin. I would try that first. Good luck!

    Bloating can be caused by a bacterial disease. Usually bloat doesn't cause bleeding externally, but can result in red streaking on the body or fins. Bleeding may be the result of injury, possilbe another fish nipping at the ill fish. Things that can cause bloat in most fish are a poor diet, and/or poor water conditions. Changing the diet and offering occasional live foods can often help. Antibiotics can be used as well to fight the infection. Read the section above about types of fish diseases (see bacterial), also see the section on Dropsy for the most common type of fish bloat and how to treat.

    The Baby Bi-Orb is a really small tank which makes water quality tougher to maintain. Being around 4 gallons in size, it can really only support a single Betta or about 4-6 very small fish, like Guppies or Neon Tetras. Feeding needs to be closely monitored so excess food is not left in the tank, and partial water changes need to be done on a regular basis.

    If it is black ich, which is caused by a parasite, it probably won't hurt them, but is easy to cure. Just go to a pet store and look for an available black ich or black spot treatment. You could also try a salt bath on just the fish.

We have beeen having a lot of problems with my grandsons new tank. We have had it for about 2 1/2 months now and have lost several fish in it. Some very quickly, and some after about 2-5 weeks of acting strange. I have had my water checked, and adjusted it or changed the water accordingly. Changed my filter packs often, But after water changes on several occ, even partial changes, the fish seem to be gettng shimmys, followed by a listlessness, keeping to bottom of tank a lot except for feeding time, and gradually getting off balance and gradually dying. Could it be something in our water, from the pipes, or do they just have swim bladder disease going on? No red streaks, growths , or fungi present just shimmys and off balance with loss of weight, wasting away and off balance. Only one aquarium so far having this problem out of 4. So seems like a disease of something, more than water problem. Deborah

    Well, there could be any number of things wrong. First, if you use tap water, do you make sure to put dechlorinator in? Also, make sure to perform water changes regularly, but only change out 1/4 to 1/3 of the water at a time. Have you had all 4 aquariums the same amount of time? If the other tanks are older, they are probably already equalized correctly, with the right amounts of nitrates and other parameters. The new tank may just need more time to cycle and establish itself.

I have a goldfish that I have had since it was hatched in my pond, about 10 years ago. I have had it in a huge tank for many years now, and it has been growing large. Lately it has been getting round lumps under a scale, then the scale falls off leaving a white scar and the lump goes away. Much like the gold fish on your homepage picture. It also has some small white dots on its forehead so I have been treating it for ich, but they are only a little smaller and the treatment time has been exceeded. I am getting ready to do a water change and put back in my carbon filters. Any ideas about what is wrong, or what else I can do?

    Lumps and bumps that suddenly appear are usually infections. If due to bacteria, it usually resolves by rupture (like a boil) pretty quickly. The white liquid that oozes out is pus that is formed when the white blood cells ( immune cells) die while killing bacteria (in general). DO NOT TRY TO POP OR SQUEEZE THE LUMP. Like a boil in humans, squeezing can cause regurgitation of the pus into the blood stream of the fish with deadly results. It is also not a good idea to seal a draining wound unless it is bleeding. The most common bacteria of GF is Columnaris and aeromonas.

    Wounds that are white on the edges and red in the center are aeromonas. Those that are red on the edges and white in the center are generally columnaris. Both are gram negative bacteria TMP-4 is a sulfa antibiotic with trimethoprim which can be put in the water and mixed with food (that is what Romet B is). It is still effective against most, but not all gram negatives bacteria.

    It is very important to move fish with wounds to a new bucket of freshly aged and salted water every day to move them away from bacteria and/or parasites in the water.
