does anyone have round gobies?

I just a pair: male and female from fishermen. this guys are pretty cool. already started eating a day after being put in the tank. male is solid black, i thought it was different species first. but they have change into breeding colors.
p.s. i am in europe. so no invasive species comments please.

None here, how big are yours?

i would say 5-6cm. they are straight out the river. i was waking along the bank and ask fishermen if they had any for my native project. they are 3 or 4 gobie species here in Dnepr. Also, there is land locked black sea pipefish which would be my next dream fish.
