Thought I would share a photo of an interesting E. caeruleum that I collected last weekend.

Edit: the photo looks like half of the caudal is missing, this is just poor photography.

Did that coloration last?

What did you do to that darter?!?!
j/k
Interesting looking rainbow darter there. Was this collected in a similar type stream as the ones we collected when I was up your way? Is it the only one with the funky coloration?

That's pretty different, must be a genetic deformity. Does it ever change color? Like from pale to dark?

Tattooed it!

Very similar stream, but with way more fish. And yes out of at least 50 rainbow darters, this is the only "funky" one!

No, so far about 5 days, its coloration has been very static.

I have seen this type coloration on benthic fishes sampled by kick seining. Many times these fish get abraded or stepped and and develop this darkened region. This region then turns into a bacterial infect usually and the fish rarely makes it. Has yours shown any problems at all?

Dustin, None at all. It is feeding well. I also see no evidence of damage or infection. Time will tell.

No Kidding! I can tell that its pigmentation, and not blackspot. That is really cool! Want to breed designer darters? :lol:

I figured it had to be blackspot but didn't pay much attention.

I caught dozens of Rainbows ini this location and this was the only one that looked this way.

I thought that as well but if it were a bruise or something than would it have such distinct markings? You can clearly see the diamond shaped marks down the side. I have actually seen hand shaped bruises on trout from being handed to hard in hatcherys.

May be I am wrong, but it looks like pigmentation to me. I rarely find darters with heavy blackspot infestations, even from the same location in which every common shiner, and blacknose dace is riddled with it.

I honestly don't know for certain. I just thought I'd put the pic up.

I assumed it was blackspot since the fins also had the spots on fins whre you would not expect any pigment.
