While there is nothing like seeing tropical fish in their natural habitat, many people who want to take a little of the sea home with them start their aquarium. Part of the joy of owning and caring for an aquarium is the effort that goes into collecting the fish you wish to add to your habitat. Tropical fish, in particular, are a great addition to any aquarium. Whether you’re just beginning to assemble your collection or updating your existing selection, here are some of the most popular tropical fish that are a delight to enjoy in your aquarium.
Guppies
Guppies can be colorful tropical fish that are relatively easy to catch. They’re also easy to care for and excellent for beginner aquariums.
Neon Tetra
While these freshwater fish are tiny, they’re a step up from guppies if you want something with more vibrant colors. These are schooling fish, so you’ll need at least half a dozen.
Swordtail
These little guys are known for their playful interaction with each other. While they aren’t aggressive, having at least two females for every male is a good idea to keep the peace in the tank.
Angelfish
Angelfish are an especially popular tropical fish selection due to their graceful movements and elegant appearance. These fish are colorful and diverse, from striking solids to bold patterns.
Cory Catfish
Known for their peaceful nature, Cory Catfish is an excellent addition to your aquarium. These scavengers prefer hanging out at the aquarium’s bottom and eating leftover food.
Black-Skirt Tetra
You’ll need a larger tank for these silver and black striped fish, but it’s well worth the effort. These docile schooling fish typically prefer flake food and an occasional treat.
Harlequin Rasbora
These black and metallic orange schooling fish make a colorful addition to any aquarium. Docile in nature, these fish prefer swimming near the top of the tank.
Zebra Danio
These fish are hardy, active little swimmers with pronounced black and white stripes. While these fish can be somewhat aggressive, they can do well in mixed groups of fish when correctly cared for and fed.
Otocinclus Catfish
These widespread algae eaters help keep things nice and neat in your tank. These peaceful schooling fish require little attention other than occasional algae wafers to supplement their diet.
Cherry Barb
Considered to be somewhat aggressive, these slow-moving fish are pretty active schooling fish that tend to do well in tanks when mixed with other active species. If you want color, go for the brighter red males.
