Hi... I have a new (one of four) shebunkin goldfish that has developed a slightly swollen belly, amber colored and slightly bulging eyes, and a few red spots on her body. She was in a 600 gallon aquarium with other fish, and began to act sluggish three days ago, but would still eat when they were fed. I've moved her to a hospital tank because I noticed the red spots and the problem with her eyes. She now will make an attempt to go after her food and eat, but will immediately spit it out. Any ideas as to what this is and how to treat it?

    Goldfish are prone to bloating, called bloat or dropsy. Bloating can be caused by bacteria that are commonly present in all aquariums. Healthy fish rarely effected and are only susceptible when their immune system has been compromised by some stress factor. Stress factors can be poor water quality, diet, or aggressive tankmates. Usually bloat doesn't cause bleeding externally, but can result in red streaking on the body or fins. The mortality rate is high, but if caught early it may be cured. The best treatment is to move it to a hospital tank, add salt at 1 tsp per gallon of water, feed high quality foods, and treat with an antibiotic.

I have had goldfish in an outside pond for over 2 years. I clean it out monthly and have great filters and aeration and they have grown well and healthy but this last 2 weeks I noticed scales on the bottom of my pond and have lost 6 goldfish in a week. I'm gutted as I love my fish can anybody help please?

    If scales are falling off it may be bacterial, and it could indicate something is wrong with the water. Improved water quality can help to enable your goldfish's immune system to resist accumulating problems. The best thing may be to take a dead fish (within about 1/2 hour of dying) to a pathologist to determine the exact problem.

    I'm so sorry to hear about the problems your fish is having.  It could very well be that it is suffering from what is known as Hole-in-the-Head Disease or Head and Lateral Line Erosion Disease (HLLD or HLLE). See details and treatments above for this under Hole-in-the-Head Disease. Unfortunately this is a rather common ailment for such fish as the Flower Horn Cichlid, Oscar Cichlids, and a number of other large South American large cichlids. It can even affect the common angelfish. It could also be Hexamita, which is a disease with very similar symptoms to HLLD.

    Everything you are doing is good. The azoo bacteria treating powder can help with preventing/treating any secondary infections that may result. Under Hexamita above you will see a treatment using the drug metronidazole. Metronidazol can also be effective when treating Hole-in-the-Head, so would be another treatment you may want to try. Wishing you and your fish the best!

Well it started when I went to a larger tank almost two years ago. Now got a new tank with problems, lost a lot of fish, couldn't get it to clear up and then my largest oscar got hole in head. Treated it then but still cloudy water and now have two large jack dempseys and platy and catfish they are my only fish left. Tank is 100 gal and is still messed up I'm so frustrated. It's cloudy bad and has a green hue, yes I do water changes, don't know what to do now. The jack has something wrong with his mouth, he doesn't close it all the way and it's got like a flap of skin on top inside. Doesn't look the same as other fish I'm so upset I have 4 other tanks and they are beautiful please help me.

Hi All, I have a 20 gallon tank with three Gold fish and two Blue johanni cichlids. From two days one of the gold fish is swiming only on top and not eating anything as well not active. I have changed the water around 30% and added fresh water treated with commen salt 3%. After that also Fish is in same condition. I fear a lot that it may die as already I experienced. What should I do to protect my fish?

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.
