DETROIT (WDIV) - A Michigan man might need a bigger bowl for what he reeled in last week.

It's a goldfish, but not like one you've probably ever seen.

Mike Martin loves to fish. He has been fishing for 20 years.

What Martin pulled out of Lake St. Clair last Saturday is of a size few ever see.

"Basically, I was doing what I always do, trying to catch perch and I thought I had a big perch on. Um, definitely not a perch," said Martin.

If you give little goldfish room to grow, they get big. This one is nearly 15 inches long.

"Everybody wants to just dump them out their sea wall and let them be free and this is what they turn into," said Martin.

Is this record book stuff? Hard to say. The record fish list in Michigan is long, but it doesn't include goldfish. Martin says that's because goldfish are notoriously hard to catch.

"I've been fishing this lake for 20 years, first one I've ever caught. I called my dad the second it came out of the hole. I didn't know what to do with it. Asked him what I should do with it. I've never caught a goldfish. What do you do with a goldfish," said Martin.

His father told him to put it in a bucket and take it home.

Martin says he plans to mount it on the wall.
