Fish are fish are fish—right? Wrong: Fish are much like people. Some really like each other and make for good neighbors. Some shouldn’t live across the street—or even in the same town—as other fish. That’s because fish have mannerisms, habits, and behaviors that mean they might be afraid, aggressive, or unable to thrive in the same tank as certain species.
Clownfish are no different. Some fish will make great tank mates with clownfish, while others just won't work out. While there are no hard-set rules on what you can put together in a tank, having an idea of which fish will compete with each other for food and even position in the tank can go a long way in taking care of clownfish and ensuring a peaceful fish tank.
But how do you determine that? First, it starts by knowing this fact: You can’t buy random fish, or even random accents and fish tank décor, without it affecting the health of what’s there or what else you want to include. This useful chart sorts through lots of saltwater fish and helps you find tank mates that ensure healthy in-home tanks, every time.
