I noticed late last week that my uaru had what looked like a wound or scrape on his side but thought very little of it becouse he has scrapes on his head and body on a pretty regular basis becouse he thinks he is a lot tougher then he actually is and is constantly trying to push around the severum and nicaraguan he hangs out with.
Normally they go away after a few days but this one started to get bigger, and he seems to have lost appitite.
I moved him to a quarantine tank and put in Maracyn Plus last night incase its a bacteria thats the cause, but I dont really know..
I am really worried about him becouse he is one of my favorite fish and it would be terrible to lose him.

It is difficult to tell anything from the photo.

It should only be either bacterial or fungal or a combination so you are probably off to a good start.

Try and insert a better photo or use something like sharesend.com to upload the original and provide the link in a post.

Kind of looks like a heater burn.
If it's growing it might be some sort of ulcer.
Do you have any "suckers" that might be latching on him in the night?
CAE,Pleco?

Good call by Ghostdogg and better reply than mine.

I was also thinking of a heater burn.

Well it looks like you have caught it in it's early stages, so don't stress out too bad.

Cottony fuzz would be a description of fungus. You can either medicate with drugs or try salt. If you chose to medicate, just go to your LFS and tell them the problem and they will reccomened a product to you. It is also a good idea to continue with the antibiotics to prevent any secondary infection.

If you chose to go with salt, first make sure that the fish will tolerate salt, certain species can't. Also, try and use iodine free salt such as aquarium salt. Though, the good old RTR states:

Sodium chloride is the familiar white crystalline material in just about every kitchen. Table salt as purchased at the local supermarket in this country also contains iodide and anti-caking compounds.
Iodine is a halogen, and is required for vertebrates in its ionic form. Iodine is the element; iodide is the ionic form. Do not confuse either of those with "tincture of iodine" which is a topical antiseptic and quite toxic. Iodide is necessary for our metabolism as an essential part of thyroid hormone, which is our metabolic pacemaker. Soils in wide areas of this country are deficient in iodine, and this lack can result in goiter (hypertrophy of the thyroid gland, effectively from insufficient iodide intake). Thus the practice arose of adding iodide to salt intended for human consumption. This was the safest (the levels of iodide are minute) and surest way of protecting the population from this deficiency as salt is ubiquitous (all but universal) in food processing and preparation. The levels of iodide added to table salt are so small that any water-living vertebrate or invertebrate would be pickled in brine well before toxic concentrations of iodide could be reached, so that particular urban myth is without foundation. In fact, a number of our tank inhabitants need iodide- most crustaceans have a significant demand for the material, and a number of fish can develop goiter in captivity from the lack of iodine - African Rift Lake fish seem especially prone to this. The often-discussed toxicity of iodide could be considered urban myth #1.

As for salt dosage, see the table here and also at the bottom here.

Plus you may want to try and figure where the wound came from, as mentioned it doesn't look like a fight wound.

I have one farowella but I honestly doubt he did it becouse he barely moves from his spot under the log, anything is possible though.. and however it happened its become alot worse in a day or two, he is in a quarantine tank atm with maracyn and salt and he is just sorta laying on the bottom, not even trying to swim.

ok so the sore/wound is now all the way from his lateral line to the bottom of his stomach, it has spread by about 25% since yesterday and the white cottony fungus has doubled WTF, how long should I keep the Maracyn+ and salt up before trying something else? its been 3 days and he is steadily getting worse..
I really dont think he will last the full cycle of maracyn the way things are looking

If you net him try to put pimafix or melafix directly on the wound with a q-tip/cotton swab.

I'd repeat this daily until the wound stops spreading.
The fish might not like the feeling but this will stop the fugus from growing on the wound.
Fungus makes everything worse.

I've tried Maracyn, but mela & pimafix seem to work better for me.

Assuming that it is a heater burn it could just be further damaged tissue dieing off. If the fungus is spreading you could consider increasing the salt content (what are you at now?) or probably a safer route would be to go with a fungicide. Personally I am not a fan of the melafix/primafix combination, it is essentially a herbal extract and is a nice "first try" but if the condition is worsening I would personally go with the pharmaceutical medications. The maracyn will prevent/eliminate any secondary infection. It doesn't look infected, but hard to tell from the photos. Maybe try and post an updated high res photo.

I'm so sorry! It is terrible to have something like that happening. Usually clean water and salt can take care of most wounds but this seems quite agressive. Have you done searches through Google to identify what it might be? There are several sites that have fish illness descriptions and pictures. Also, be very careful to protect yourself. You should be wearing gloves or at least be sure that you have no open sores and that you wash your hands well.

hey guys, im almost certain at this point that its Flexibacter columnaris, the area around the open wound looks exactly like the "saddleback" that apears in the pictures when I google it. What really sucks is all the conflicting information I have read, every site says somthing differant, some say maracyn works others say it does nothing, some say raise the heat some say lower the heat, etc.

I am at 1 tbsp per 5 gallons of water right now I have also started usingAPI liquid fungus cure also tried putting a salt paste directly to the wound this morning, so far nothing and the "saddleback" portion of the infection has spread further since last night. My Uaru is about 4-5 inches tall and the infected area is going from his stomach almost to his dorsal fin now, I will get a picture tonight if I can, the API turned the tank green so its kinda hard to take a pic.

ya well That guy says maracyn works...NOPE, and its hard to feed the fish food laced with antibiotics when one of the side affects of the fish being so sick is it dosnt eat.
So I picked up some triple sulfa and am throwing that in to the mix, somthing has to work.

There is a difference between Maracyn+ and Maracyn.

Essentially there are two types of bacteria, gram positive bacteria and gram negative bacteria.

Some antibiotics work better on gram positive bacteria while others are more effective on gram negative bacteria. It is actually somewhat common to run both Maracyn and Maracyn-2 at the same time to ensure that both bases are covered. Other approaches are to use broad spectrum antibiotics such as Furan2 and Triple Sulfa.

On a positive note, it looks like you have a solid diagnosis which can be half the battle in itself and you will be well versed to recognise the problem in the future.
