A normal or typical person who completely nerds out when it comes to aquariums or fishkeeping. Coined by Cory McElroy of Aquarium Co-Op in a live stream on YouTube on 19 October 2020. The term has rapidly spread in usage across the aquarium hobby and is now frequently encountered in a number of aquatic hobby contexts.
Most people wouldn’t guess, but I’m a huge nerm.

You know you’re a nerm when you try to grow green water on purpose.
