My Dempsey is showing severe signs of stress (extremely pale) going on two weeks. In that time I've done rock Salt therepy; four water changes of 40-50%; ph test 7.2. No visible signs of disease. I am hesitating to further treat until cause of stress has been confirmed. I believed the stress was caused from decaying matter. I feed it's fellow tank mates with gold fish. The last feeding many of the gold fish were dead before I got them home. I introduced them to my hungry fish before making sure it was safe to do so. I've lost two of my fish to this and fear for the rest. The fish have shown very little improvement from cleaning the tank. New symptom of rapid breathing showed up tonight! No other visible ailments. Suggestions welcomed!

I have a 15 gallon tank with all platies and 2 'o' named small algae eaters.. There are two of the fish currently with bad white all on the eyes and it doesn't look good. What should I do? I am tempted to clean the whole tank out but I am also worried this can affect humans too. Should I wear gloves?

    It is possible your fish are suffering from ich from some sort of eye problem. I wouldn't recommend changing all the water, because that will upset the chemical and nutrient balance of the water. Change out about a quarter to half of the water and siphon out any gravel on the bottom. Feel free to use gloves, but most likely you will have no problem with any disease you could catch. Then, start the tank on a round of antibiotics such as Maracyn. If you are treating for ich, you might want to raise the temperature of the tank for a few days and treat with quinine hydrochloride or just quinine.

    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.

    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.

    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.
