J&M Aquatics and Pet Center

Setting up an aquarium is an exciting and colorful addition to your home! If this is your first time having one, you may be asking many questions, like what fish pair well together. Having compatible fish is vital for the safety and peaceful living of the fish. We will also discuss the environment, number of fish, and species of fish to consider in this blog.

Fish Tank Size

The more space the fish must freely move around, the more they will be around each other. A close-knit tank makes the fish anxious and irritable; you do not want your fish to end up hating each other. A 30-gallon fish tank is the minimum size for fish to have room to grow and live in harmony. However, a smaller tank means you want less fish.

Fish Age, Size, and Gender

  • Younger fish can better adapt to new friends than older fish. Starting out with young fish will also mean they live longer, and you do not have to replace the fish as often.
  • The size of the fish is also important to think about. Try buying fish the same size so one does not prey on the other.
  • Fish gender can also make or break the relationships between themselves. Fish are biologically more territorial than females when it comes to mating. A tank with more female fish and only one male of the same species is a smart idea.
