Since version 1.14, it is impossible to feed ocelots with pufferfish or tropical fish.

Before version 1.14, ocelots could be fed with raw cod, raw salmon, pufferfish, and tropical fish. However, since the update, they can no longer be fed pufferfish and tropical fish. Currently, only raw cod and raw salmon are viable options for feeding ocelots. Moreover, cats cannot be fed with these types of fish either.
