That's why we always recommend selecting fish from the same community, ensuring the best possible balance. These communities include:
These colorful fish are active and easy to care for but are aggressive toward other tank mates when defending their territory. Furnish your tank plentifully, providing decoration African cichlids can use to establish personal space.
Like African cichlids, these guys are both personable and easy to look after. They're less aggressive toward tank mates, but all fish need to be similar in size to ensure compatibility. Most reach 6 to 8 inches in length, but some (such as the oscar) can grow to be more than a foot long.
Goldfish come in a number of interesting varieties with beautiful, flowing fins. Both laid-back and hardy, they make ideal pets for beginners. Goldfish can live up to 20 years, depending on their environment.
These eye-catching creatures are known for being abundantly colorful and active. Many species do best when kept in schools of five or more. An aquarium with a large school of colorful tropical fish can be very impressive.
Semi-aggressive tropical fish share the vibrant colors and animated personalities of their non-aggressive counterparts. They tend to bully smaller tank mates, so it's best to make sure all semi-aggressive tropical fish in your tank are similar in size.
