Guppy With Blood At Base Of Tail

[Proterra]

Hi there,

I have a guppy which has become quite thin and also developed what looked like fungus and also has what looks like internal bleeding at the base of it's tail.

My water stats in tank were ammonia 0, nitrite 0 and nitrate about 20. All other fish in that tank seem fine for the moment.

I have separated the fish and am treating it with a bacterial medication and also some melafix. Please tell me if that is totally wrong thing to do. I have to re - treat the tank in another 2 days time with the bacterial medication as it's to be used every 4 days. It has been in separate tank for 2 days now and most of the fungus has gone and the fish is swimming better and still eating but is tending to hang sometimes at the top of the tank but by no means all the time.

Any suggestions as to what else I could do or if I should change what I am doing at the moment.

Thanks.


The guppy is about 5 or 6 months old and its normal home has guppies, platys and neons in it.

Is the thiness through the fish not eating, not the writer of this information below.
Also can you name the med you are using.
Symptoms:

Fish may have reddening at fin bases, blood streaks throughout the fins and body, small hemorrhages around the eyes. Dull listless behavior and lack of appetite may also be present.



Cause:

Systemic bacterial infection caused by various bacteria, including Aeromonas, Pseudomonas and Vibrio. The illness is often brought on by poor water quality or as a result of parasitic infestations or other infections. These bacteria enter the blood stream and circulate through the tissues causing inflammation and damage. Inflamed blood vessels in the skin and at fin bases stand out. Blood vessel and heart tissue damage cause hemorrhaging and consequently leakage of body fluids into the abdomen, which may lead to Dropsy.



Treatment:

Water conditions must be improved for all fish in the tank, regardless of how many fish are infected. Check your water’s Treat with Kanacyn or Tetracycline as well as with a medicated food if the fish will eat. If parasites are suspected, all the fish in the tank should be treated with antiparasitic medication. Using salt to help restore osmotic balance might be helpful.
