comet goldfish dorsal fins and tail turning white?

Question

why is that happening? plus the dorsal fins look like they have half fallen off and that area is all white. i dont leave the fish in too dark conditions either. any info would be appreciated.

Answer 1

Well, this is called finrot, and it is caused by poor or very bad water conditiones
there are 2 ways to treat it
either with salt and heat or with maracyn TC
I would go for the maracyn TC
do a 50% waterchange and start treatment for 10 days
once the 10 days are over, do another 50% waterchange, and then a 25% waterchange after 3 days
then you need to do 25% waterchanges once every week



Hope that helps
good luck

Answer 2

This is absolutely NOT ich!! Light deprivation will not cause fish to lose fins or to become "bleached". You've been getting a lot of very poor advice.

Comet goldfish are usually kept indoors in tanks that are too small. Comets need nothing less than a 55 gallon tank with heavy filtration. If you fish is being kept in a bowl or smaller tank this is cause of the fin rot and/or cotton disease your fish has.

Your water quality is most likely very poor. Goldfish in healthy water and properly sized tanks/ponds generally don't get sick.

Test your water quality. Ammonia and nitrites should be 0ppm, pH should be 6.5 - 7.8 and the tank temp should be 60-72F. If you don't have test kits, take a sample of your tank water to a local fish shop and they will test it for you.

Partial water changes of at least 25% are required every week for goldfish. Testing water quality for ammonia, nitrite and pH is also mandatory every week. Nitrates should be tested in a cycled tank at least twice monthly.

If your goldfish is in a bowl, it has little chance of survival at this point.

Goldfish are among the more difficult fish to keep. They live well in excess of 15 years and require large tanks, advanced knowledge of freshwater water chemistry, the nitrogen cycle and a willingness to spend several hours a month on tank maintenance.

You will need to ensure this fish is in good quality water, and treat it with a good anti-biotic.
