Eel - Injury Or Something Else?

[DeathStalker]

Have you tested your water?

Yes

If yes, what is your ammonia?

0 ppm

If yes, what is your nitrite?

0 ppm

If yes, what is your nitrate?

5 ppm

If I did not test my water...

...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.

Do you do water changes?

Yes

What percentage of water do you change?

21-30%

How frequently do you change your water?

Every week

If I do not change my water...

...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.

I just noticed this on my Tire Track Eel. On a human I would think Ringworm, but no, nothing has been added to the tank and yes, I do multiple water changes per week and test the water. Hoping it's just a slight injury.

I know the Nitrate is slightly elevated, and I'm doing a water change tomorrow.
Thanks.

Haven’t seen something that before. Looks like it got stuck on a intake. Keep the water clean and watch the area. Tankamtes?

 

[DeathStalker]

Intakes are Fluval FX6. I'm thinking maybe jammed herself on part of the driftwood or one of the rocks. Just never done that before, only minor scrapes and stuff. No tank mates that would ever give her an issue (she's 3').

That is odd...maybe a burn on a heater? Nice fish by the way

You obviously have a lamprey infestation in that tank...

I obviously have no idea. Really looks like what kno4te suggested: an injury from getting temporarily stuck on a filter intake. You said you had Fluval fx6 filters; I'm not familiar with them. Do they have something in their construction which makes this impossible?

 

[DeathStalker]

No, the FX6s do not - they have a filtered grate, nothing like this. I suppose it could be a heater burn, but the heater is a Cobalt solid unit (they're flat, not cylindrical).
