Okay, I'm really starting to get ticked about this.

Shortly after I purchased my 7 rainbows (10/15), the largest female was bitten by a gourami and lost a few scales on her side. She then appeared to develop fungus (rainbow fish are very suspecticle to fungus) that spread over her entire right side and up over her dorsal fin. She had the classic "saddle back" look. I took a close look at all the rainbows and noticed that two of the males had very small threads on their lips. I added salt, 1 tbsp per 5 gallons, and treated the entire tank with Prima and Mela fix. She looked like she was improving and the fungus seemed to be almost gone, however, the area underneath was recessed and grayish in appearance. I assumed that it was from the injury/fungus and would improve. On 10/23, I saw that the threads on the males were gone and I decided to move the female to the hospital tank where I could keep a closer eye on her. She died from chlorine (so I thought) 5 mins after I put her in the tank. I forgot to dechlorinate the water. I do not know what the chlorine or chloramine content of our tap water is as yet. I'm waiting for my test kit. I now think it may not have been the chlorine that killed her

Three days ago, 10/28, I noticed that my second largest female was displaying fungus in the exact same way the first one had. She also had a recessed grayish area and one of her fins was affected. She was not using it unless she had to. She was with the school, but staying at the top of the tank. I added salt and APPLUS+ Anti-Fungus to the tank (malachite green, arciflavine hydrochlorine). It didn't help at all and she died last night. One minute she was shimmying in place at the top, the next she was by the filter, then she was suddenly in death throws: she flew all over the tank, flipped onto the glass and died.

Her death was very much like the death of the one I had put in the hospital tank and thought I killed with chlorine.

Does this sound familiar to anyone? I'm starting to think that it's possible that my rainbows fish are being attacked by childonella or some other parasite and are developing the fungus as a secondary infection. I can't find a lot of information on this parasite and no pictures of infected fish to compare. Anyone?

My Tank - 36gal Bowfront, planted, flourite substrate
Current Parameters: Ammonia 0, Nitrites, 0, Nitrates 5.0, pH 7.4

I had problems getting this tank to cycle and I thought it was done (I used Bio-Spira) when I added the rainbows. Somehow it went haywire. I'm sure the stress of trying to re-establish the bacteria hurt all the fish and lowered their immune systems.

I'm scared for the rest of my rainbows. NONE of my other fish have visibly come down with this, but I have lost 1 corycat to reasons unknown and several neons to gouramis and who knows what else. I currently have in the tank: 5 Boesemani rainbows, 3 leopard corycats, 1 Agassiz's corycat, 2 neon tetras, 1 glo-lite tetra, 2 platies, and 5 ghost shrimp

I do *not* want to lose any more rainbows!!!! I have 1 more female that is now hanging out by the filter instead of with the school, so I bet a dozen donut she's sick as well.

Help?

Your ammonia ect, is at good levels, or so it would seem. What type of test kits are using for ammonia,nitrite and nitrate?

There seems to be a water quality problem to me, even though your tests aere showing otherwise. Fish usually will recover fine from injuries if the water quality is good. But as you say they are being attacked from other fish and if this is very severe, it could be very stressful on the fish involved and as you may know stress can also cause disease. BUT, you said a cory and other fish also died which again make me believe that it is a water quality problem.

What type of filter do you have and how long has the tank been running for?

Aquarium Pharm., test seems to be fine and reads well for my other 4 tanks.

The water *was* bad, it's been fine for the last 5 days.

No, she was attacked once by the gourami, shortly after I got her. I removed the gourami. I removed all the gouramis. He was also eating my neons and I'm sure the other two were having a few nibbles here and there as well.

The neons were partially eaten/harassed to death by the gouramis that are no longer in the tank and/or victims of my tank recycling. I've never had much luck with neons no matter what darn tank I put them in.

The corycat I can't explain. He had no symptoms and he was found dead the day after my tank stablized. No fungus or anything.

Tank has been running since Oct 9 and *fully* cycled since 10/27.

I had a Magnum HOT when I started (used Bio Spira) and replaced that with a Penguin 330 on 10/20. The tank seemed to be cycled (readings all 0s) by 10/15, but on 10/17 everything went wack. Ugh, I can't retype that stuff, I've carpal. Here are the links to where I posted my tank problems:

Deffinately a water quality problem. Your fish are probably still suffering the effects from all the toxins in the water. They will have been weakened quite a bit from the cycling process and could show signs of this for the next few weeks. The effects could be permanate and you still may have fish die over the next few months. It is very hard to tell with this kind of thing. All you can do is keep your tanks water quality good by water changes and vacumming and providing the fish with a sufficient filter(If your tank is cycled then the filter should sound like it is fine).
 
I hear what you are saying and I agree on all counts, however it doesn't explain the grayish recessed patches on the rainbows. It doesn't look like cotton wool or fungus. If there is some sort of parasite at work here, I need to find this out. I really think the fungusy growth is a secondary infection.

Should I keep the salt up? Should I medicate to help prevent further problems?

What parasite are you suggesting? Some pics of these Fish would do wonders.

The fish are dead. I have no pictures. As I said in my original post:

"Does this sound familiar to anyone? I'm starting to think that it's possible that my rainbows fish are being attacked by childonella and are developing the fungus as a secondary infection. I can't find a lot of information on this parasite and no pictures of infected fish to compare. Anyone?"

The description of this parasite's attack that I *did* find matched the grayish area that I have seen on my fish under the fungus.

I just want to research it in order to rule it out or in.

Ok, Roan, I am figuring you had a ammonia spike by adding seven fish at the same time, which could have been the start of all your problems. The disease is really secondary until you find out what caused it, It will do no good at all to treat the disease without fixing the original problem. I had a situation a few months ago where i drove 1hour away to get some fish, and wound up buying 6 fish total, I knew I would have issues so I picked up a bottle of melaflex and Fungas cure and Ick Tabs from Jungle labs, and sure enough, in two days i had ick and fungas mouth. so i treated with Ick Tabs for 1week and then Fungas cure for one day. I have never had any problems with my rainbows besides ick. which was easily curable. so in short we need to figure out what is causeing all these issues, your water looks good now but may have had an issue with ammonia when adding the 7 fish, and surly stressed the heck out of all the fish, which in return has caused you problems
