Well, I had another fish die today. What was a seemingly healthy fish yesterday was dead today. This is the 3rd fish to die with the same markings on the head. The fish is already gone, should have photo'd it. I'll try to explain.
The fish have a reddish tint on the top of the head between the eyes. The Warpaint Shiner that died today had what appeared to be a bit of blood under the skin on top of the head along with the redness around the head. There is no swelling or any other visible signs of problems. There where no signs of problems as of yesterday. I'm scared that something may wipe out my tank, or maybe in coincedence. Anybody ever seen something like what I described?

What is the concentration of ammonia, nitrite, and nitrate in parts per million?

When seining in warm weather, I have seen shiners that were in the sein too long start to look like what you describe. Red on top of the head and generally lethargic when put back in the water. They usually recovered within a few minutes of being put back into cool water. In the case of these fish, I am guessing this was due to thermal stress and/or lack of oxygen. I don't know if this is helpful or not, but thought I'd throw it out there. Did you notice the red coloration on any of the fish before they died?

No rapid breathing, appetite loss, color change, or behavioral symptoms within a day before death? And one dead fish at a time, while all other fish look and act healthy? That's weird. Maybe a virus?

Josh, I believe you showed me a photo of one of these fish. The first in the series of photos was pretty descriptive. I believe it was a head shot of an orangethroat darter. Do you still have these pics? If so could you post that photo? I think that photo might help with a diagnosis.

Thats the puzzling part.
#1 Fish appears 100% fine before death. Eats, swims, breathing normal, no lesions/lumps, etc...
#2 Fish dies suddenly. Reddish area on top of the head, no open wounds
#3 Even after several hours in the tank (fish death 2 could have been dead for over a day) the eyes are still intact, they usually go fast. The body seems slow to decompose
1st fish died and I let it go as old age/ dwindles, though the top of it's head was red. 2nd died roughly 2 weeks later, same odd red area on the head. 3rd fish, roughly one month later same red area on top of the head. 2 Darters, 1 shiner.

I cropped it down. Here is the spot I've had on all three dead fish.

If not viral, then maybe:
Theory 1) studying too hard in school & their brains fried.
Theory 2) vampires
Theory 3) aquatic vampires (Belostomatid bug or fishing spider)
Theory 4) kids spearfishing with a dissecting probe
I will send your pic to Dr. Noga at NCSU vet school.

I actually thought about there being a leech in the tank, but it's too coincedental that all three have been the top of the head.

Here's an interesting link: http://www.epa.vic.g...phillip_bay.asp
*keeps looking*
It looks kind of like something ate away at the tissue in between the outer skin and the brain of your fish. The tissue is really thin and transparent there.
Do you have access to a microscope? I'd be interested to see what the slide looked like. And did you do a necroscopy on the corpse(s)?
Also, I sent the photo to Dr. Oldfield, the professor of ichthyology at CWRU.

Thanks Erica, although I had read alot of this before in seperate forums this was nicely put into one area.
I'm posting this on the forum instead of Private Messaging you because I want other people to have this resource as well, if they need it. It's the "fishy farmacy" disease diagnostic chart. It's a dichotomous key of symptoms that leads you to a diagnosis. I've used it many times.
Here it is: (scroll down to "advanced fish disease" section) http://www.fishyfarm...m/symptoms.html
Examples:
Changes in Behavior: http://www.fishyfarm..._disorders.html

What other fish are in the tank.....any pleco's or small carp?

Response from Dr. Edward Noga, NCSU Vet School:
Hi Gerald: Hard to say without doing an examination of the fish. Some bacteria can cause encephalitis (as well as some viruses) but would need to do cultures or at the very least histo.
Best, Ed

Hi Ed - A guy on the NANFA forum posted this pic of a darter that died suddenly with no obvious symptoms, other than this reddish area on top of head. It appears to be under the skin, not an open lesion. Three fish (2 darters, one warpaint shiner) have died so far a few weeks apart. All were eating, swimming, and breathing normally up to the day before death, and the dead fish had no lesions, lumps, or other discoloration beside this spot over the brain. All other fish in the tank look and act fine. Any guesses? Is there some kind of fish encephalitis?
Thanks!
