Can rainbow sharks and catfish be in the same tank?

Yes, rainbow sharks and catfish can coexist in the same tank, but it's important to consider their specific needs and temperaments. Rainbow sharks can be territorial, especially as they mature, so providing plenty of hiding spots and space is essential to reduce aggression. Opt for peaceful catfish species that can handle the tank conditions and ensure that the tank is large enough to accommodate both species comfortably. Regular monitoring of their behavior will help ensure a harmonious environment.
