Mollies!
Being very attractive tropical fish, Mollies can come in a variety of colors and patterns. For instance, the Dalmation Molly is a hybrid color variation of the Poecilia latipinna (the Sailfin) and the Gold Dust Molly is a color variation of the Poecilia sphenops (Short-finned.)
They range from 2 - 5 inches in length and can live 3 - 5 years with proper care. Molly fish are peaceful, hardy, social, active, and easy to care for!
One of the most unique characteristics of these fish is that they have the ability to survive in both freshwater and saltwater if acclimated slowly and carefully. Mollies, along with their platy cousins, have been kept successfully in freshwater, brackish, and saltwater conditions, although the last is not recommended for the novice aquarist. They originate from very diverse environments: freshwater, brackish, or even waters of various salinity, temperature, hardness, and acidity levels. Even in freshwater tanks small, measured amounts of salt per gallon can be beneficial.
Though not considered schooling fish, Mollies are usually more interesting to watch when they are kept in groups, since they will display a much broader range of natural behaviors when kept together. They prefer to be in a group of mollies, but can also make for good community fish if there is enough room in the tank. Though not typically aggressive - and may at the most nip at a few other fishes' tails - they will even establish their own hierarchy within their group!
Males are usually dominant, so it may be best if keeping multiple mollies to have them be the same gender or have one male with more than one female so as not to cause any unnecessary stress or accidental breeding. In same-gender tanks, keeping more than 3 mollies together is still better than a single one alone to diminish the potential for bullying. Having better-than-average filtration will be helpful, too, due to the molly's hefty appetite. Mollies love a thickly planted tank since they are omnivorous and will enjoy eating the algae from the plants as well as swimming about at the middle/upper levels in the water. This in combination with other decorations is also great for providing the fish some shelter, but also be sure to have some open, well-lit areas in the tank, too.
The Molly's versatility, hardiness, friendliness, and the different, bright colors they come in make them a very popular fish sought by beginners and experienced hobbyists alike!
