I have a half dozen black mollys, free, they are GREAT for starting a new marine tank. They do well in either fresh or salt water(even breed in salt water). They are easy to catch after tank has cycled. All you do is throw a little flake food in and scoop them out. 1 million times better than damsels! All I ask(not that I am checking) is after your tank has cycled, you pass them on, free, thanks Jolly.
