Unhappy Advice needed for Cories - possible velvet??

Hi,

I need advice. Last week I saw a fine coat of white in large spots on a couple of my cories. I treated with API general cure, thinking it's velvet.

One of the cories looked pale and passed the day after treatment.

After the second dose, I still have the large whitish areas and another cory has a large pale looking spot.

Any ideas? I hate to re-try a cure that didn't work, but don't know what else to try. Someone else has post here a black moor they lost using the same treatment. I'm hoping someone can recommend something more effective - or challenge the diagnosis.

I know you'll ask about conditions. I'll run tests tonight, at work right now. The plants in the tank are doing very poorly, I have to wonder if that's telling me something? The tank is a 46g with:

3 Adorable butterfly loaches
1 Black Phantom (2 others had mystery deaths a couple months back, no new fish in since then)
3 Sidh... loaches
6 Neon dwarf rainbowfish - these guys hated the treatment, were spooky and wouldn't eat.
6 Cories

At last test, I had no ammonia, nitrite or nitrate. I do need to retest to confirm, especially since I treated. Plants were amazing a couple of weeks ago, but are suddenly fading fast.

I'd appreciate it someone with more expereince could help me get through this!

Thanks,
Sue

I keep reading on the net that fish with velvet will flash and be gasping. My cories act perfectly normal.

Could it be fungus instead? This appears to be just right up against the body, I though fungus would stick out fluffly like - am I wrong?

I'd highly recommend look through all pages here, see if the pictures help you ID what you're dealing with first; once you know what you're actually indeed dealing with proper medication will be easily found http://www.tropicalfishkeeping.com/t...diseases-8179/
Meanwhile ensure a GOOD water quality, possibly do w/c rather 2x week at about 25% rather then one big one.

Thanks, Angel. I think I may be dealing with columnaris. The pictures look right and don't mention the scratching that I don't see and is associated with velvet.

Every website I look at says to treat with something different, as does the LFS. They sold me Melafix. I don't htink I have a great deal of faith in it, but I'll give it 2 days. I do like that it's mild for the sake of my rainbows.

I really like the notion of frequent smnall water changes.

Thanks,
Sue

Columnaris is pretty nasty stuff man. I had that in my tank and it killed pretty much all of my live bearers. I treated the tank with salt, pimafix, and melafix for a week. The disease was killed and I had one guppy that lived through it all and 3 neons.

Well, my tank's been treated with melafix and pima fix for a full week now and the cories look the same. When I left, I had one that had a terrible spot on his side and more on his head. In the heads spot, there's a place where it looks like he's lost some skin. The rest of them had mild spots on their heads.

Hubby treated while I was away and I came home to find the one that looks bad, looking exactly the same and one of the others dead. I hae no idea what to do! I'm going to head to the LFS store and look for something anotch stronger. I hate to do it, but I'm travelling again next week and can't monitor.

Hubby tries while I'm away, but his eyesight could be better.

Bummer! I hope it stops soon for you. Did you also use salt? Salt is pretty good too along with other treatments.

I have been unfortunate enough, to have battled columnaris a few times. Its quite common in new fish around here. You can try Maracyn-Two. Salt will also help.
The nice thing about Maracyn-two, if water quality is good, you can treat for 5 days with out a water change. This might be helpful, since you will be away. A lot of columnaris meds require daily 25% water changes.

Primafix is said to work well for mild cases, but sounds like you need something a little stronger.

I've treated columnaris with Furan 2 before successfully. Maracyn and Maracyn 2 will work also. Be sure to keep an eye on your water parameters as some of these meds may harm your biofilter.
