Red Spots and fins

Hi

Can someone help me. I have a could water tank with gold fish in. About 5 days ago 2 of my fish died. I got 3 new fish about 2 weeks ago and I think 1 of them had a illness. Now the rest of my fish is geting red spots on them and ther tail fins is also geting red. What is it and what must I do. The fish also ly on the floor of the tank.

 

Do you have an air supply (pump) in the tank?

Perhaps copy the template in the sticky and complete it in this thread. That'll greatly help with the diagnosis.

(I know, now that I've seen the wonder of bubbles I'm trying to remedy it to everyone!)

 

Yes I have an air supply to my tank.

 

What other filters are you running in the tank what is the tank size and fish sizes.

 

pH? Last water change? Substrate? Rocks/plants?

 

If you can see blood in the spines of the fishes fins, this normally speaks to water quality.

 

sounds like you have an ammonia spike, test the water
When last have you cleaned out the filter? or done a water change

 

I have done a water change on Saturday. I also cleand out and change the filter. It is a 33 L tank with only stones in (no Plants)

 

Bacterial Diseases
Red Pest
Symptoms: Bloody streaks on fins or body.
Red Pest is called such because of bloody streaks that appear on the body, fins and/or tail. These streaks could proceed to ulcerations and possibly lead to fin and tail rot with, in severe cases, the tail and/or fins falling off. As the disease is internal, external treatments are usually not effective, except in very slight cases. In slight cases, treat the aquarium with a disinfectant and clean the aquarium as best as possible. Do not feed a lot while the aquarium is being treated. To disinfect, use acriflavine (trypaflavine) or monacrin (monoaminoacridine) using a 0.2% solution at the rate of 1 ml per liter. Both disinfectants will color the water, but the color disappears as the disinfectants dissipates. If the fish do not appear to respond favorably, discontinue disinfections.
Then add an antibiotic to the food. With flake food, use about 1% of antibiotic and carefully mix it in. If you keep the fish hungry they should eagerly eat the mixture before the antibiotic dissipates. Antibiotics usually come in 250 mg capsules. If added to 25 grams of flake food, one capsule should be enough to treat dozens of fish. A good antibiotic is chloromycetin (chloramphenicol). Or use tetracycline. If you feed your fish frozen foods or chopped foods, try to use the same ratio with mixing. As a last resort add at most 10 mg per liter of water.

 

Hi @Jan G ...
how many fish in 33l? Could be an overstocking problem leading to a amonia spike....But more likely your new aditions introduced a parasite to your tank... first check your water quality,then consider using a basic anti parasite medication...

A word of warning though...if you stick to the one inch / gallon rule of stocking...your tank can only support 2 goldfish...this leaves them a bit of space to grow....

 

try googling up a bit on this: Septicemia

its the presence of bacteria in the blood (bacteremia) and is often associated with severe infections.

lost a bala shark like that once, when i was very ignorant about fish. my tank was way overstocked to begin with, water quality was very very poor..

do some reading up on it.. i think you'll find answers
