When i first noticed white spot, i grabed some treatment. How ever this seem to take a week or so to clear up.
I used salt, i thought 'table' salt was ok. So used this. The white spot was gone in 2 days and fish were all ok, back to normal.
Noticed white spot again last week (4 months after previous spout) Used salt again. Cleard all ok,.
I know a few will screach at me for useing table salt. But whats the difference if it clears it all up.

Sorry to bump such an old topic, but this is the thread i found by googleing "black fin".

I have a 1 gallon tank, the goldfish had started to get black on the fins, we changed the water, the gravel was absolutely filthy, its all nice and clean now, as a boost to recovery i added a teaspoon of pure sea salt flakes, the type all the posh chefs use, i hope that will be OK.

Hello Sara, welcome to the site.

The problem is that 1 gallon is absurdly small for a fish that should grow to 8-12" in length. The black you see is the result of ammonia burns and unless the fish gets a much larger tank immediately it will die. Salt is not a cure all and will not in any way help your fish.

Obviously you care about your fish or you wouldn't be searching the internet trying to find out what's wrong so please do yourself and your fish a favour and read about the nitrogen cycle and goldfish care in these articles. Any questions please ask

Woops, sorry, its a 6-7ish gallon tank.

This one:

okay, its still a quarter of the size needed for goldfish but its not an instant death trap.

How long has the tank been set up, how long has the fish been in there?
Do you use an dechlorinators, detoxifier, balancers, medications or other additives to the water?
Do you have any test results? (ammonia, nitrite, nitrate, ph, temp)
Is there any chance of you getting a 30 gallon tank and large filter for Christmas?

Sorry I'm going to resurrect this old thread for a while,

I'm helping to treat a friends tank which currently contains 6 guppys, the tank is an aquastyle 620: 90l capacity. Params are Ammonia: 0 Nitrite: 0 Nitrate <20ppm

Just done a 25% water change.

All 6 guppys are showing various symptoms, spending most of their time at the surface of the tank with their mouths permanently open, stringy poo, tatty looking fins beginning to rot away with black and white edges, bloating and general lethargy.

One fish is particularly bad and seems to have some serious balance problems, lying on the bottom for long periods of time before trying to swim about in a topsy turvy style then giving up and sinking back to the bottom.

I have dosed with aquarium salt at 0.5g/l and was considering an isolated salt dip for the very poorly fish, is this a good idea? I'm not sure if its a good idea to return the fish from a strong saline environment into another (albeit much weaker) saline environment.

Does anybody have any experience with this?

Many thanks

Sorry Betta James, I cant answer that one, but I thought it was a good place to ask this question.

What is the situation with corys and salt? Some books and websites say its a no no, others say its a myth. Can anyone clear it up please?

Hi BettaJames

I've posted on you other thread now with regards to salt treatment
