Well, largemouth bass and smallmouth bass are also sunfish... depends what you mean by sunfish. I've personally caught green sunfish at 10 inches and have caught bluegill and rock bass that were definitely pushing the 12 inch mark, even caught a crappie on a live bluegill while bass fishing that came in at 17 inches.that's epic dude. Well this disproves the people who say "sunfish reach 12 inches" since the state record is only 10.5 inches. Personally I think that sunfish usually only get to 8 inches max.
