A 10-gallon tank is recommended for neon tetras. Just make sure you're not housing them with predators. It's also perfectly fine to group neon tetras with other fish. While you'll want to focus on creating groupings of a least six, the sky is really the limit when it comes to how many you want to keep if you have ample space. This is definitely a case of "collect every colour" because tetras thrive in large groups. The next colorful freshwater fish is the neon tetra is a staple of aquariums because this variety is so visually striking and easy to care for. I personally think adding a dozen of these rose-coloured fish is a perfect way to create a colourful undersea bouquet! However, you should consider a 20-gallon aquarium if you plan to keep a school of six or more. This is a hardy option that can work in something as small as a 10-gallon aquarium. I often find myself thinking that these fish look like rose petals that have been sprinkled inside an aquarium when they catch my eye. The harlequin rasbora is an excellent option if you're looking for a beginner-level fish with extraordinary color.

You can reduce the "edginess" of cherry barbs by keeping these colorful freshwater fish in small schools. While cherry barbs are not outgoing in the company of fish, they do well when it comes to sharing aquariums as long as they have plenty of room to swim openly. You can expect your cherry barbs actually to appear white or silver the rest of the time. The distinctive red hue of the cherry barb actually only appears in males during spawning. What is notable about the cherry barb is that this fish doesn't actually keep the vibrant coloring that makes it famous all of the time. Life really is a bowl of cherries for aquarium keepers who bring in the cherry barb fish! Like the fantail guppy, the cherry barb requires beginner-level maintenance. Make sure to follow the rule of providing 2 gallons of water per guppy when sizing everything out. Easy-to-care-for fantail guppies often require 10-gallon tanks. You can expect your fantail guppies to grow to approximately 2.5 inches in length. Guppies do prefer to be housed in small schools. Just make sure you're not housing them with any potential predators. The base color of a fantail guppy is typically yellow, lime or teal.Ĭolorful aquarium fish aside, fantail guppies make great additions to robust aquariums because they tend to thrive when housed with other varieties of schooling fish. Watching one glide by can be like watching the way precious metal catches brilliantly in the light. What's more, the fantail's movement in the water is especially striking as a result of splinters of silver and black. The fin really stands out during movement because it's quite large in comparison to the rest of the body of the fantail guppy. The fantail guppy actually owes its name to the large dorsal fin that fans out broadly from its body. In addition to offering the benefit of beginner-level care needs, the fantail guppy helps to create a very active aquarium via the eye-catching fluttering of its tail. The fantail guppy has a lot of fans due to sheer ease of maintenance.
