Got some awesome new corys. They had been at the shop for a day before I bought them. They are monsters. Anyway, one of them has some white spots/frayed looking fins. Hope the pics help. Ideas? Treatment? I've already turned the temp up to 86 (should I go higher?).



Over the last 3 days the fish has gotten worse. He now has fluffy white stuff covering roughly 33-50% of his body and fins. Yesterday I dipped him in methylene blue for about 15 seconds. He appears no better today. All 11 of his mates are doing well and active. He tends to stay hidden in one place and only rarely comes out, and when he's out doesn't appear to be swimming as well as the others.

Here is a picture. Hope it helps, seems to have a fluffy white film. Suggestions?

also, did a 50% water change yesterday with aged tap water treated with prime. I'm unsure how to proceed because I've heard conflicting things about corys being sensitive to salt, meth blue, and meds. He's currently in the tank with 11 other C. sterbai, 1 L177, 5 SAE's and 5 Otocinclus as well as plants. I have an available 10 and 40 gallon tank for quarantine or treatment as well as buckets for quarantine treatments/dips.

It looks like a fungal infection. You say you use prime as your dechlorinator? Well, Seachem also makes a really awesome anti-parasite,fungal,viral called Para Guard. Try it out, it works very well. Kordon AquaHerbals makes a product called Ich-Attack. That works well for fungus. Thats what I used to protect my baby cories when I was hatching them out.
By the way, I just bought 6 small C. sterbai and they are awesome. I can see why you'd want to do anything to save them.
Good Luck

Were I in that situation, I'd consider a hospital tank real quick. Unless you have a tank full of sick fish...I wouldn't treat the whole tank.

I would use the 10, it's small enough. No substrate. Put a heater, filter (No carbon)...I use homemade filter for my hospital tanks, and a few pieces of 1in PVC (acts as logs and gives them some place to hide. Also has a benefit of being easy to clean once the fish is back in the main tank.)

Nice thing about using the 10 is most meds are geared towards that measurement.

This is exactly what I did. I treated 2 days with Jungle Fungus Cure and 5 days with just erythromycin. After further research I decided he probably had Columnaris which would be bacterial despite the "fungal" appearance. He seems to have come through with no ill effects beyond looking a little "bleached."

Good to hear. Thanx for the update
