AboutDavid St Experience I have been in the hobby for over three years. I am currently setting up an online business to sell aquatic plants. I have raised and bred guppies, cichlids and goldfish. I currently keep over 200 differnt kinds of fish and over 100 different kinds of aquatic plants. I also have been part of a fish rescue group that take in fish people no longer want. I currently have 16 tanks at home plus two hosptital tanks, 1 snail tank, and a nursery for plants. I work in an aquarium so I have some experience in other areas that I do not feel I am an expert in. The most important piece of information that I would like to convey here is the fact that I love fish and have for many years been rewarded by keeping fish. I would like to be able to help people share the same kind of satisfaction that I have had from keeping fish.

Answer Hi Ellie:
You have described a disease called specimecia. It is usually caused by poor water quality. Sometimes it appears as red spots and sometimes you may actually see blood in his fins. Goldfish need to be in a large aquarium of at least 20 gallons preferably 30-55 gallons. They can live 20-30 years but seldom make it past a year or two in captivity. Goldfish can also grow to be quite large I have seen 20 inch goldfish (including tail)but the thing to remember about goldfish are that they are very messy. Their tank needs 50% water changes at least twice per week in 30 gallon tanks or change 50% every other day in smaller containers. Goldfish should never live in bowls. They need lots of room and water that circulates gently.
I would change 50% of the water in the tank and add aquarium salt. I would also make sure that the gravel in the tank is cleaned using a gravel vacuum. If you do not already do so I would get your water chemistry tested. Most aquarium stores will test your water for free. If you do get your water tested let me know what the chemical values are so that I can provide you with further assistance. Even the clearest of tank water can become deadly without notice. Regular water changes along with tank cleanings will help your fish safe and healthy. The oldest goldfish on record was 43 years old and she was a goldfish someone won at a carnival. Keep me posted... dave
