WHy is my fish has blood marking under her skin?

Question

She have blood marking under her skin. and She is fine.

Answer 1

"Just me" is on to something with Ammonia poisoning...very possible and likely scenario. Although, why she is recommending to test Ammonia with a Ph kit, I don't know;)

Regardless, you need to do 2 things immediately...time is not on your side. First, test the water, you can take a sample to a full service aquarium shop and they'll usually test it for free. You need to insure your water is being tested for 3 parameters: Ammonia, Nitrite, and Ph...all are done with seperate tests.

No matter what the water test reveals, you are most likely going to need to change some water right away. Start with a 30-50% water change NOW, then take the water to get tested, preferably 2 samples pne before the change and a sample post-water change.

Let's start with that and go from there.

Answer 2

It would help if you said what kind of a fish it is (fish and chips?? joke.)

If it's a goldfish then red scales or red lines on the fins can be a sign of sickness, usually due to dirty water. Give the tank a proper clean, change the water, and get some 'Disease Safe' and follow the instructions.

The marks should clear up within a few days.

Answer 3

I would say that your fish may have ammonia poisoning. Test your PH levels. You can get a PH kit at most super stores or pet stores. They come with the chemicals and instructions on how to heal your fish tank. Ammonia can build up in a tank that's over crowded or has not been cleaned, or if you've overfed your fish. PH is the most challenging part to regulate in a tank. Actually I would assume that Fishguy is right. I could easily be incorrect on the specific name of the testing method (PH). The level of ammonia is most likely the issue though.

Answer 4

How do you know the fish is fine, just because it is swimming around? It sounds to me like it could be stress which has caused raised veins. You need to get some Stress Coat and perhaps a tonic Tetra No 10. Also a part water change could be beneficial. Mainly you need to find out why it is stressed, is it being bullied. Good luck, I hope it will be OK.

Answer 5

I would say either ammonia poisoning (you can check this by testing the water) OR septicemia, which is a bacterial disease: http://www.fish-disease.net/diseases.htm .

Both of these would have symptoms of bloody streaks in the body or fins. If you're doing regular water changes of around 20-30% weekly, your tank is cycled, and no ammonia is showing up in water testing, this would be more likely.

It's also possible that your fish scraped against an object in your tank, or was "finned" by a catfish (these have spiny rays in their dorsal and pectoral fins).

Answer 6

try researching your fish.. plus is ther any other fish in the tank? there is a such thing as fighting fishes u know..

Answer 7
