Active fish like danios and barbs need longer aquariums which means a rectangular design with more horizontal space will suit them well. Territorial fish, like cichlids, need lots of bottom space so stay away from narrow or taller aquariums if you plan on keeping this type of fish. But there are fish that prefer tall and narrow fish tanks, too. They can be ideal for less active fish like discus, angelfish and gouramis. While the tall, narrow shape doesn't offer as much swimming area or surface area for gas exchange, they might fit into your room nicely if it has a smaller space for an aquarium. When deciding on your next aquarium purchase, think about the types of fish you want to keep and the amount of space you have, then buy the largest aquarium that meets your needs.
