Oscars are big, boisterous cichlids that are often seen as cute little juveniles in pet stores, but in less than a year they’ll grow to the size of an American football!

While many sources claim that 55 gallons is enough for one adult, due to how big they get and how much waste they produce a larger volume of water (with efficient filtration and regular maintenance) is highly recommended

Although caring for them can be a challenge, they’re also quite rewarding due to their intelligence and “puppy-like” personalities!

And as long as you can manage their size and lifespan, they’re relatively easy to care for. Just don’t feed them goldfish: it’s unhealthy, unnecessary, and downright unethical.
