Fish that are described as having a very special diet will have a carnivorous preference for food. For example, a guppy with this attribute may eat carnivores instead of the usual fish food, and it will completely ignore any regular fish food. Fish with this attribute will eat guppies, carnivores, or ultravores instead of their usual fare.
- Rocky - Rocky is a small guppy and voracious eater that eats ultravores despite being disproportionately smaller than them.
Assuming January 1st of 2017 is day 1 and December 31st is day 365, fish with the very special diet attribute are available from The Fish Emporium on days that begin with an odd number and end in a 1 as in 11, 31, 51, and so on.
- A breeder that has this attribute can have a preference for guppies, allowing them to feed themselves by eating their own offspring.
