Help! my black moor fish has white spots on it and the tail seems to be breaking apart.?

It sounds like a fish disease called ick.Go to your local pet shop and buy ick treatment.Until that time put just a tiny bit of salt in the water.

i gotz a good explanation for this! what you think that its ich is actually is that the fishold enough to breed. i think that the fish's tail is coming off or something is because it has a tail rot. From site Treatment: It is best treated with an antibiotic. There will be one best suitable at your local pet store. Make sure it states that it treats Fin or Tail Rot. In some cases a secondary infection or fungus will appear. If this is the case, treat the fish for the fin rot and then proceed to the fungus problem. the white spots isnt a disease

Take a sample of your water into PetCo and have them test it - they can recommend what corrective action to take...something is off with your water.

My boyfriend has worked for pet store and thats where the expetes come from. If you want a good tank I would recommend pulling out the fish that are in there and treat them in another small tank. Now, Disassemble the tank. Thuroughly clean the tank and all components. After you put the tank back together use RO water (or filtered water) to fill up the tank and the let it run for some time. You will need to add Cycle (R) to the tank and get the ceramic piece that will grow bacteria and put it inside the filter. DO NOT put the other fish into the tank until you are 100% sure that the other fish are healthy. Also, take the water that the fish are currently in and take it to a pet store and have it tested.

do not add any more fish. you have a serious water quality problem. try changing 25 % of the water then add more ick medicine, make sure you remove carbon from the filter first. wait 48 hours and repeat. keep doing this untill problem clears up. and never add more then 1 fish per 5 day period. a ten gallon tank with good filtration can handle about 1 inch of fish per gallon. but not gold fish, gold fish= 1 inch of fish per 2 gallons, do not include the back fin as length of fish when calculating this.

Do you have children? Happened a while back when my daughter poored milk in the tank. Check with a tropical fish store. Not a pet store cause they've got too much going on to effectively diagnose fish. Change the water for them as usual adding more of the old with the new to acclimate them.

there is something in the water that is killing them, i had that happen when i was young and had fish, take a sample of your water to the pet store where you get your fish, they will be able to tell you whats wrong

I fear for the life of your fish.

Guess you will either figure out what is killing all your fish or just keep on buying more hoping that one of them will live through the disease and filth in there
