There’s something very fishy about this friendship.

A man has befriended a freshwater smallmouth bass in the wild — and now they meet up every summer.

Rex Colubra was on a dive in September 2021 when he “met” his new pal. He claims the pair became fast friends — and Colubra even nicknamed the fish Elvis.

“It was like any other dive: I was checking out a new spot and all these fish were coming up to me,” Colubra, 40, told South West News Service. “I noticed one was sticking closer than the rest. He wasn’t scared even when I got out. He stuck close to the surface in the shallows.”

Two weeks later, the Wisconsin native returned to the same diving spot — and the fish remembered him and swam up to him.

Colubra fed Elvis some crawfish — and the rest was history.

It’s unclear how the fish, uh, recognized Colubra, but the diver told SWNS he recognizes Elvis thanks to a scar on his face, which was most likely caused from being caught by a fisherman.

The print-shop worker and animal enclosure maker gets to see his fish bestie every year now when he travels to the lake where Elvis lives.

Colubra taught the smart fish a call that he responds to that will help the fish find his human pal.

“I will do a gulping grunt sound with my throat and he’ll come find me,” he shared.

Elvis is also overprotective of his friend and gets jealous if he sees Colubra interacting with other fish.

“Elvis will literally just fight other fish if they get too close to me to keep them away.”

Colubra added, “He’s completely obsessed with me. He follows me around and just stares me in the eyes.”

But when you’re friends with a fish, it’s inevitable that there’ll be a few scares.

Last year, Colubra couldn’t immediately find Elvis, and he feared the fish had passed. He also refuses to share which lake his little friend lives in as a means to protect him.

“Of course, I would be sad if he had been caught. He’s my friend,” Colubra said. “There’s not much I can do to protect him. It’s the risk he runs every year.”

“I don’t like sport fishing. I think it’s immoral,” Colubra added. “If you are going to catch a fish you should eat it and not just put a hook in it.”
