Radioactive Carp

The Radioactive Carp is a fish that can be caught for Mister Qi’s Extended Family Quest, and it is one of the five Legendary Fish required for that quest. It shares its sell price, healing effect, location, and hook chance with the Mutant Carp. Like the other quest fish, it can only be caught while the quest is active, but more than one Radioactive Carp can be caught during the same quest.

It is found in The Sewers. Outside of the quest, it is not available to catch. In bundles, the Radioactive Carp is not used.

The fish has a small but useful role in dyeing: it can be used as a green dye ingredient at the dye pots in Emily’s and Haley’s house at 2 Willow Lane.

A Radioactive Carp can also be placed in a Fish Pond. Its pond capacity is fixed at 1 fish and cannot be increased, which makes it one of the most limited pond species. The pond’s only possible output is Radioactive Carp Roe. Its production table is:

• 32 Fishing XP granted at population 1, with a 72% item chance and 36% overall daily chance
• Nothing at population 1, with a 28% item chance and 64% overall daily chance

Because the pond can never hold more than one fish, it serves as a very simple source of roe rather than a scalable production chain.
