yes sculpin....could be prickly but i would need a full side shot and as many fin shots as possible both lower and top fins flared will help allot, need rays to count to get an accurate ID ..hard to tell some of them apart..looks to spotty for the prickly... Try and get a shot of his upper and lower fins flared.
what is your tank set up for this guy?
and how big is he?
you got him out of the creek and its not spring anywhere quiet yet..might be warmer for you but its hard to acclimate a creek sculpin in to a home tank..what temp is he in?
