Help With a Freshwater Fish!?

[MossyFroggyLove]

Heyoo everybody,

So, ain't a saltwater related topic here. But, i really need help with my freshwater fish, i think its a carp.

So the tank dimensions are as follow, l×w×h, 29.5×14.5×17.5 inches. The water is about 80% the height of the tank. The fish is about 6-8 inches long.

So, this is the only fish in the tank, and recently i spotted a new wound. Is this an abbrasion or a bacterial infection?
Here is a picture of the whole fish on the side with the wound And here is a picture of the other side of the fish
The tank also has a bunch of water sprite floating on the surface. Any help/info is greatly appreciated.

Yes, this is a carp, or Koi fish. In Japanese Koi = carp, and is pronounced like 'Koe EEE' if anyone cares to know

These are usually very hardy fish, but the mark to me looks like possible Urenema, if it's not just an injury of some sort. Is it on just the one side?

#fishmedic who's good with freshwater fish ailments?

Nice info! I didnt know that before.

Is it on just the one side?

Yes, its just this one spot.

I'm hopeful that this is just an injury and it will heal on its own, but I tagged the R2R Fish Medic team, and I'm sure one of them will be able to tell if this is an injury or something else.

It's a good looking fish for sure, I am far, far from an expert in Koi, but it looks to be something like a platinum variety.

They are usually quite hardy and bullet proof, but keep the water as clean as possible and watch for any signs that it's getting worse.

The bacteria called Aeromonas, is one of the causes.

The bacteria prefer to active in comparatively low water temperatures, so the disease almost doesn’t happen to tropical fish.

Look into this. Antibiotics will take care of it. What are you running for temp?
This is common in carp/koi fish. I see this during the winter on carp. Yes I fish haha.


From a koi medic I know:
(do more research if need be)

Oxytetracycline (Terramycin Aquatic): Bath treatment at 10–20 mg/L for 10 days minimum. Avoid in hard water above 250 mg/L CaCO3 (calcium bonds tetracycline and reduces efficacy). Water changes before treatment reduce organic interference.

Enrofloxacin (Baytril): Requires veterinary prescription. Better penetration into infected tissue. Available as injectable (more reliable for serious cases) or bath treatment. Increasingly used for Aeromonas that shows tetracycline resistance on culture.

I just contacted a nearby exotics vet. They asked me to try Seachem NeoPlex. And if there are no improvements, then i should bring the fish in for a checkup.

So, i think i will try Seachem NeoPlex first.

As for temp, its around 28-30 degrees celcius.

These are cold-water fish, I'd drop the temp to just room temp (20C to 22C). There's no reason to heat these fish, they do better at room temp and bellow.

I actually dont have a heater in that tank. That just my normal room temp. Right now it's 31.1 degrees in my room.

Yes Neoplex is a good one to start with.
