I found this guy early this morning, I released him shortly after as I had no ID'ing material with me. Anyone know what it is>? Found in the Fox River, Waukesha WI

Your fish is a johnny darter (Etheostoma nigrum). WI does have a similar species, E. chlorosoma; however, there range is rather limited and they are not found in Fox River.

I was really suprised with how large he/she is. I had never seen a darter as long as my finger before lol..

Thanks for IDing it before me, I saw it was brown with darker spots along the lateral line and was about to guess tesselate. I would have been wrong as it is outside the tesselates range. (just checked the tesselates range on natureserve to make sure).

If you look closely, it has a bump on its forhead. Any ideas of what this is? I thought it reminded me of a rhino, but I cannot tell why it has it or what caused it.

That's Johnny the Darter.

I heard somewhere that the species got its name because of one kept as a pet named Johnny. Apparently keeping darters goes back quite a ways.

Is the nose bump the trait to distinguish Johnnys from Tesselates?

I doubt that's the case. People just like to give people's names to organisms, from Johnny Jump-up to Robin Redbreast to the numerous fish named "Jack".

I love these guys... they seem to be adapting well to take life.. already have flashing of the male to the female to entice her!

The distinguishing characters for the two are mainl 11 soft dorsal fin rays for johnny, 13-14 for tesselated. Also the infraorbital canal (line of pores around the eye, may need a scope) is interrupted in johnny and not in tesselated. But the easiest way to tell them apart is usually drainage.

If you don't already have them, set up some small caves in your tank. They spawn on the underside of rocks etc... and the male will guard the eggs. He will also get bold vertical bands on his sides and his head will turn jet black as he displays for the the female.

There are plenty of caves in the tank (I would know as my fish experience is primarily in pleco/dwarf cichlid breeding) I will post images of the tank later as my camera is recharging. I do have a video on youtube of them both just after arraiving into the holding tank.

Does that show breeding interest?

is there anything visual that I would be able to use when I am at the river to pick up more females? Is there certain barring in the fins or anything visual, or do you just have to hope to find males in breeding dress and throw them back?
