Yes you heard it right, a saltwater molly. Sailfin mollies are a beloved classic when it comes to aquariums, but did you know they could live in saltwater too? Mollies can breed naturally in brackish, fresh, and salt water, making them a very versatile little fish. Reaching only up to 4 inches and being great algae eaters they can be a great addition to any reef tank. Being very hardy and with a reasonable price tag they are some of the best starter fish for new hobbyists.

Being as they don't get larger then 4 inches the minimum tank size for mollies is a 20 gallon aquarium. Make sure there is plenty of live rock and hiding spaces as they love to graze constantly for algae and micro foods. You will want to feed them once to twice a day, and they will readily accept most types of food including brine, mysis, pellets, and flake foods. They are completely reef safe and non aggressive so avoid keeping them with larger predatory fish.
