Any ideas what this little guy is? He came in a bunch of fathead minnows

I'm going to say Brook Stickleback. That looks like 4 or 5 spines in the pic but if there's 3 it could possibly be a Threespine Stickleback.

Nice find regardless, sticklebacks are good tank fish if you have good experience with other natives. They're more challenging than say shiners or darters but I'm sure you could keep it man. Most will only eat live food (Blackworms I've heard are a good diet for them) but some can be weaned on to frozen.
 
I was DESPERATELY hoping my contacts where foggy and it was a walleye fry hahaha thanks dive!
it has 5 spines by the way haha
 
I didn't even think about walleye. It does look a bit like a walleye fry but I doubt it is, I'll let some others chime in but I'm 99% sure that's a brook stickle. Don't be sad about it though, Sandwr species (Walleye, Sauger, Xander) aren't good aquarium specimens anyway, they just kind of mope around in the corner all day. They're beautiful fish to keep just not active.
 
haha you definitely nailed the ID man, I googled them, never heard of them before! Apparently its pretty common to get them with fatheads. I'll have to keep my eye out, I like the look of these guys.
 
Beware of their fin nipping. The sticklebacks are not good for community aquariums and will hounding other tankmates to death just like gambusia.

pssssh he is so busy sparring with the pumpkinseed all the time that neither of them bother the other fish anymore lol.
 
Dive got it right. Stickleback. I've kept 2-3 species before but it's been 25 years ago now. Man, I am getting old!!!
 
hahaha well I now have 2 of them in the tank. The baitshop I get my fatheads from has given me 2 sticklebacks and a mosquitofish so far lol. Waiting for spring when I start getting baby bullheads in the mix.
 
Nice, yep it's a brook stickleback. I get them in my minnows all the time. They do have some good personality, they remind me of a sea horse. I've had one by it self in a fish bowl for over a year. They are pretty territorial, I tried to put another one in there and he just attacked it. He eats flake food and frozen food.
