Conversation Heart Fish

From HallsWiki

A rare and overwhelmingly undesirable aquatic creature, the Conversation Heart Fish is easily identified due to its bright pink scales, heart-shaped body, and the fact that it has "FISH" marked on the side of it in big, red letters. Inedible to all but the most hungry, the Conversation Heart Fish has an unusually chalky and stale taste for a living organism. Its taste is so repellent that even the Dreadnought avoids it.

The only time this species of fish is sought after is during the Valentine's Day Fishing Tournament, when Darkhawk Lake is temporarily stocked with them. Once the tournament is over, the fish are discarded. Possibly into the Elevator Shaft.
