What fish do eels get along with?

Eels are voracious predators and will likely eat any fish they can fit in their mouths. Some fish that can coexist with eels include larger, more aggressive species such as cichlids, oscars, and catfish, as well as peaceful community fish such as tetras, barbs, and rasboras. However, it is important to note that eels can be territorial and may become aggressive if they feel threatened or if their food supply is limited.
