In the wild, their diet consists of smaller fish, crustaceans, and insects.

PRO TIP:Blackjack fish are opportunistic feeders, consuming a variety of prey items including insects, crustaceans, small fish, and algae. To keep Blackjack fish healthy and active they should be fed a varied diet of freeze-dried or frozen foods supplemented with live invertebrates.

In captivity, however, their diet is a bit different. While they will still accept smaller fish, crustaceans, and insects, their diet is primarily made up of pellets or flakes designed specifically for them.

While the diet of blackjack fish in the wild may vary depending on what’s available to them, in captivity their diet is fairly consistent. This is because their diet is based on pellets or flakes that can be easily found in pet stores.
