Strange swollen looking lumps

[HAAAAAAAA]

I just noticed these on my white eyed eel, what are they? Some type of cyst?
None of my other eels have them

Looks like remnants from scars but can also be nutritional or bacterial. Assure Nitrates are not elevated as high no3 has adverse effect on eels. I suggest a broad spectrum antibiotic such as Seachem Neoplex, best done in separate container to assure no advanced signs develop along with added o2 using air stone

Can I treat him with kanamycin? since that's what I have on hand right now, i highly doubt that it's nutritional deficiencies since I make sure to soak pellets and infuse them in small fish and feed him it whole, I did see a hook scar when i brought him in but that was a long time ago, i didn't expect it to get worse now, could it also be my recent vinegar dosing which could've irritated the wound?

No vinegar dosing as it can impact their protective slime coating. Scar could have started this and im leery on kanamycin but you can try partial doses

What could I try besides vinegar dosing? My nitrates are indeed on the higher side

Personally, my best success has been doing daily 2-4 gallon water changes which not only reduces the nitrates but replenishes all traces daily
Dont let this recommendation scare you as it takes me up to 10 mins a day and I do it while watching the news as I can hear it and change water at the same time

Can you get a clearer photo? Does the skin look intact over the lumps, or are they open? Do you think these appeared suddenly, or could they have grown over a few days and you just missed seeing them?

The skin is intact over the lumps, these might've happened over time but I don't know about that exactly, I'll try to get a clearer picture

If they are internal, with no broken skin, adding antibiotics to the water is unlikely to solve the issue, even if the cause is bacteria.

If that's the case is there anything I can do? He is still willing to eat happily whenever I tap on the glass, I'll send a picture right now but sadly the quality isn't good since my main mobiles camera got it's lenses broken hence it can't focus

Apologies but this is by far the best i could've gotten, but thanks so much for the help jay hemdal i really appreciate it, I'll get some seachem focus, what are the medications I should use for this guy? i currently don't have a proper equipment to check his weight, but looking at his side and the time I held him in my net i believe he should be close to 500 to 700 grams

I’d try oxytetracycline if you can get it. What other antibiotics do you have available? I can look them up in my formularies…..

Thank you so much! I'll try to find a soluble powder of it

I currently have
Metronidazole
Kanamycin
Erythromycin

Kanamycin can be toxic if dosed too high.

Erythromycin is pretty specifically used orally against kidney infections. It works against gram positive bacteria. The oral dose is 25 to 50 mg per kg of fish body weight daily for 5 days.

Metronidazole has a long history of oral dosing in fish. The dose is easy also - just 1% metro in the food, daily for 3 to 5 days. It is effective against anaerobic bacteria. If these are bacterial nodules, there is a good chance they are anaerobic.

Thank you so much! Can I first try metronidazole and work up to other antibiotics if there isn't any improvements?

Is metronidazole toxic if dosed orally in higher concentrations than recommended?

Metro seems to be low in toxicity, it can be dosed up to 3% by weight. Trouble is, it is very bitter and even at a 1% dose, some fish will avoid eating it. I’m hoping, because eels gulp their food, that the bitterness won’t factor in too much in this case.

Unfortunately I wasn't able to start treatment because the item which I had ordered (seachem focus) hasn't arrived to me yet, but after taking another look at the eel there seems to be a skin opening now, one side of the swollen lump has decreased but with a opening.

Do you recommend me to start the treatment today right away by administering the antibiotics in the water column or do I wait till I get the seachem focus and Administrate it orally? I will get the focus a day after tomorrow

Tough to say really - these sound like cysts that are rupturing. If they don’t, antibiotics in the water won’t help.
What antibiotic would you add to the water?

I thought of adding kanamycin since it's broad spectrum but then again, after taking a closer look, the second lump which is on the right has a small opening but it doesn't seem to be directly on the bigger lump but rather a little away from it, this is indeed something i have to worry with since if I move him to a qt there's the risk of him not eating if i indeed need him to eat


Do you believe that these rupturing cysts can be severe if the treatment is delayed? It might be the cause for him to randomly act dead and upside down at times but not always
