    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Ok, my goldfish has black on the tip of its fins, always have. It has ick right now, but i noticed that its body not has a weird blackish tint to it. is this another disease/ just..weird..lol.
 
my goldfish did the same thing when I first found out it had ick. If you have any other goldfish in the tank I would remove them into a clean water until your goldfish is cured. Ick can spread rapidly and kill off all the fish in the tank, as I have learned from experience.

Also a simple answer may be that he is just changing color. I have had goldfish that when I first got them were gold with white spots. By the time they had grown around 6 centimeters their white spots had either completely dissappeared or started to fade away.

Sorry I know this isnt a lot of help, I cant think of anyother diease that causes a fish to have a black tint.
 
What size tank do you keep your goldfish in? Goldfish are really messy as far as fish go, so they require ten gallons per single fish usually.

Also, what sort of filter are you running for the tank? and do you have live plants?
Do you know the PH levels and nitrite and nitrate and such too? ( if not you'd be wise to get a test kit to make sure that your water is suitable for your fish) Goldfish are real dang hardy... so even a simple thing like providing the correct amount of tankspace and clean water and correct PH levels and such* not doing much else other than being sure theres no ammonia buildup* will usually do them well.
 
1- "Ich" is not spelled "ick"
2- Ich is a parasite that has multiple life stages, treatment courses address the earlier stages, not the adult stage that is visible on the fish. It's important to keep that in mind when reccomending things like quaranteen courses or treatment options.
3- The number of fish that can be safely kept in a given enclosure is not based on a flat volume measurement, it has to do with the efficiency of the nitrate cycle and the O2 exchange when compared to the requirements of the individual specimins based on their metabolic needs. "Ten gallons per fish" as a blanket statement is inaccurate because it does not address any of those factors and the requirements for a specimin that's ten inches long are signifigantly different from those of a specimin that's half an inch long. Efficient biological filtration and a greater proportional surface area over a given volume are also key.
4- There are a few reasons a fish can change color. Insufficient information has been provided to draw a conclusion.

Thats about the reason why i said "Generally"( meaning not always). Sure there are a million other factors, and that would easilly have been gotten into if the OP replied. but. Generally, sure... one goldfish per 10G* tank for an adult "depending on the species, sure..". Its a pet fish, so im going to ASSume that its just a normal, run of the mill typical pet goldfish. ( comet, fantail, black moor , oranda, lionhead..so-on and soforth)
