Pompanos have hard fins. They look similar to Peter. The colors are grey and pink, but different eye colors. They first appear in An Old Friend.
Grey PompanoEditPompanos are seen in some characters’ levels, except for Peter, which is a pompano too. Grey pompanos are big in Eddie levels (and in chapter 4 (1st half) in Alien Glory). (Medium in chapter 4 (2nd half) in Alien Glory). Their eye colors are yellow.
The large grey ones eat boxfish, minnows, cod and cuttlefish and are preyed on by leopard sharks. They are driven out by the Intruder in Deep-sea discovery, but manage to come back with their last level being Midnight Snacking before they're driven out once again.
Pink PompanoEditherring, pufferfish, boxfish and cuttlefish and are preyed on by tuna and leopard sharks. They’re drawn out by the Intruder in Cavern Carnage. The small pink ones cannot eat but they are preyed on by leopard sharks and orcas. They’re drawn out by the intruder in Hazards Abound. The large pink ones eat bugs, boxfish and cod and are preyed on by leopard sharks, great white sharks and pelicans. They last appear in Madhouse and all are forced to leave by the Intruder, but the first ones manage to come back. They appears 25 times or 5/12th of total levels.
For Character pompano, see Peter.
Strangelly, pink pomapnoes are bigger than Harry. Though, when first to play as Harry it will say he's bigger than Peter, which is a pompano.
In Goliath levels, pink pompanos are one of the smallest fish he can eat. Others are also tuna, but in Harry levels tuna is big and pink pompanoes are medium. In Goliath levels, they are the same size.
