Guppies are live-bearing, meaning that they give birth to their offspring instead of laying eggs like some other species do– making them a fascinating and unique breed to observe. Plus, they show remarkable resilience when introduced into less-than-optimal water conditions when compared to other tropical fish.
With a plethora of dazzling color varieties and bold fin shapes at your disposal, you’ll be sure to find guppies that will fit perfectly into almost any home or office aquarium setup.
Size: 6 – 15 cm

Mollies come in a wide range of colors and grow only up to 3-4 inches long. When it comes to their diet, these omnivorous creatures love both plants and animals.
Plus, Mollies give birth instead of laying eggs like most other fish, which makes them especially fun to watch in your tank. If you don’t want too many in the tank, just keep one gender – they’re natural breeders and will happily reproduce if given the chance.
5. Cherry Barb
Size: 5 cm
Highlights: Love to roam in schools, bright and beautiful, and should live in groups.
About Pet Fish: These easy-to-care-for swimmers love to roam around in schools and explore their tanks. If you’re looking for a bright, beautiful fish that won’t require a ton of attention and maintenance, then look no further than the Cherry Barb. One thing to remember when introducing cherry barbs into your tank is that they’re quite shy – so you’ll need to equip your tank with plenty of hiding spots and vegetation.
This will help the cherry barbs settle in quickly and comfortably. Another important factor when making your tank a home for cherries is that they should be kept in groups of at least five, with two females to every male. This will ensure that there aren’t too many males overwhelming a single female or fighting with other males for her attention.
Besides their group living needs, care for these vibrant little fish is incredibly low maintenance. They love to eat just about anything, from dry food pellets or flakes to frozen foods like bloodworms or krill (which also make great treats.), so feeding time should be quick and easy.

Male Swordtails are especially eye-catching with their long, impressive tails, which flare during courtship. If you house Swordtails with similarly-sized species such as Mollies or Guppies (not recommended with Angelfish), they may even begin to breed in well-maintained tanks that contain some floating plants and plenty of hiding places for any baby fish that hatch.

When it comes to diet, platies will happily ingest anything you give them; however, they tend to develop quite a taste for vegetarian meals. And one last thing: if you want a lot of guppies without overcrowding your aquarium, keep things balanced by having more females than males in your school.

It is aptly named, boasting striped tiger-like barbs along his sides and an energetic personality to go with it. Tiger Barbs do best when kept together in schools of at least six.
This ensures they don’t take their aggression out on other non-tiger barbs, as they are naturally inclined to be a bit more combative than other types of fish. Impressively sized, Tiger Barbs can reach up to 3 inches long and do well with larger tankmates close to their size; otherwise, these dynamic swimmers may try to chase around smaller fry.
