Red Lettuce Slug free to a good home

Hello! I ordered a red lettuce slug to help eat algae in our 6-gallon reef tank, expecting it to be about one inch like the others. A huge monster slug (very pretty red) just showed up at our house. It's just too big for our nano. If anyone wants it, you can have it for free if you can come pick it up soon.

 

The slug appears to be about 3.5 inches by 1.5 inches.
