10 Gallon Tank Help, Not Sure Why Treatment Is Not Working!

I recently purchased 6 new fish. 2 emerald green Cory catfish, 2 peppered Cory cats, and 2 albino bristle-nose plecos. I put all 6 of them in my 10 gallon quarantine tank to first see if they show any signs of disease or infections, and only one has showed any symptoms. One of the peppered Cory’s has this weird growth on the top that keeps getting larger. I started treatment 3 or 4 days ago with General cure and e.m. Erythromycin. Can someone help me identify this infection and/or what else I should do. All of the other fish look completely healthy. They all eat and swim very much.

 

Looks like a fungal infection to me.

 

Agree this is a fungal infection and should be treated with an antI fungal. API fungal cure works. It will also help with any secondary bacterial infections also.

Thank you!!

 

Thank you!!

Your welcome. Hopefully they make a full recovery for you.

A peppered corey of mine had a very very similar issue recently.

I originally treated with general cure and eruthromyacin but after several days did not appear to be getting better.

Fearing it mag be columnaris I treated with kanamyacin and nitrofurizane. It cleared up in about 3 days after teo nv treatments of that.

I did end up losing the fish unfortunately. However that particular infection did not appear present when he died sonI think he may have also had other issues like internal parasites.

I only bring this up because I'd you do not see any improvement I would suggest possibly trying a different combo of meds.

 

nyless It could be your cory had Columnaris which can look fungal, but is actually bacterial. The combo of Furan2 and kanamycin treats it.

But OP, it looks like fungus in your case, switch to anti-fungal meds.

You could also try some Meth blue as a swab treatment on the affected area with a Q-tip. Not positive how cories tolerate meth blue (it's considered a safe treatment) but Methylene Blue baths are very effective against fungus.

1tsp per 10 gallons every other day for 10 days. Best used in a hospital tank because it can stain silicone and destroy nitrification. Meth blue also facilitates oxygen absorption, so safe to use in an uncycled hospital bin.

angelcraze, Quite possibly. However the looked very similar including the threadish like part of the infection and no other fish ever caught it which I understand is uncommon for columnaris.

The tetra fungus guard I used for the nitrofutizane part of the treatment does treat fungal infections as well.

My advice is keep an eye onnit bbn if the meds work no need to change however if you don't see improvement I would consider different meds.

Just my 2 cents.

 

Maybe, I didn't know furanol treats fungus... Sorry you lost him ultimately I lost my little orange laser cory to fungus on his head, right between the eyes, wish I had done the meth blue bath treatment. I think I used pimafix with no positive results. I'll never use those again. However, I have seen a few times that healthy fish in a healthy tank don't come down with columnaris even when infected fish are added. I've seen both columnaris and fungus in person, I 99% believe this is fungus and an anti-fungal med would be more effective than anti-parasite and antibacterial meds, especially if the current meds aren't helping.

 

Columnaris is very hard to treat and is almost always fatal.

I never cured it with infected fish, I brought them back to the chain Fish Store, but my own fish never became infected luckily! They are all doing fine 1.5 years later in two separate tanks. I'll have to be careful adding new fish to any of these tanks though because there is evidence columnaris can infect new fish even though the original infection is eradicated.

Colemnaris is scary. That's why quarantining new fish and sick fish is so important. Once the tank is treated properly for it, your usually ok. But yes to treat 1 already showing the symptoms, is almost always a waste of time.

 

Yes, although I accidentally added them to a tank with my own fish to QT, I sincerely don't advocate that and will be using a new QT tank from now on!
