Two of my oranda goldish is starting to show small red like spots near fins under the scales. One has red veins under the skin on one side of the body. I used Melafix and added salt which seem to work but new ones are still forming. They are in a 10gal tank with filter and i change water once a week. What do i do? What is it really? Is the fish abusing each other or is it something else? please help!How do i treat my goldfish? May have ulcers or parasite, i don't know. Please Help!?NO SALT! Salt and goldies don't mix and will make matters worse. They have septacemia which is caused by poor water. Ditch the meds, 25% water change now then in two days. Septacemia is caused by poor water conditions, sorry. You need to be keeping them on a weekly maintenance schedule of a 25% water change, high protein diet including fresh green veggies.
NO salt. Salt makes everything with a goldfish worse. Salt interfears with a freshwater fish's ability to utilize the water they absorb for their organs. Adding salt hinders the ability of a goldfish to not only digest foods, but produce waste. Check the temps. Lower them if you have to. Test your water.
Check your filter and your temperature.How do i treat my goldfish? May have ulcers or parasite, i don't know. Please Help!?It sounds like they have a disease - bacterial or a fungus.
If you have a good pet store where they specialize in fish they might be able to tell you more and to recommend something to treat them with.
However, if they are inexpensive goldfish you might want to get rid of them, disinfect your aquarium and equipment, and get some fresh ones as they don't cost much and the medicine may cost more than the fish.
Alternatively you might try separating the infected ones to a hospital tank. It could be that there is something in your tank that they are reacting to.
