As I've mentioned in previous posts, I have a 10 gallon aquarium stocked with minnows from the bait shop that I use to feed the sunfish and smallies in my 30 gallon aquarium. The number of minnows has been dwindling down, and yesterday I found a surprise visitor to my tank, a brook stickleback! I've never seen one before, but I'm 99% sure that's what it is. I can clearly see the 5 spines on it's back. Sorry for the crappy photo, but it's the best I could do with such a small fish that insisted on staying at the back of the tank.
I took a short video too. The stickleback has some interesting behavior. He has to furiously move his pectoral pins to swim around, and tends to stay on the bottom like a darter when he's resting. I have no idea how to care for it; I'm really hoping he'll eat goldfish food.
