I was wondering because when I think of a tropical fish, I think of salt water fish. Would a Platy be considered a tropical fish? Because I just set up a tank of them and I would like to post some pictures.

Sorry for the goofyness of the question

Yes a platy is a tropical fish. There are tons of tropicals. Mollies, guppies, tetras, gouramis to name a few.

Cool Beans, Thanks Glitter!

No problem! Let us know what you decide and remember PICS!

To me, a tropical fish is just about any fish that needs to live in a tropical water temperature LoL

Congrads on the platies

Tropical: The tropics are the geographic region of the Earth centered on the equator and limited in latitude by the two tropics: the Tropic of Cancer in the north and the Tropic of Capricorn in the southern hemisphere.
en.wikipedia.org/wiki/Tropical

So basically any fish from there is tropical, be it saltwater or freshwater. Goldfish are not coldwater (as many people believe) or tropical, they are sub-tropical based on where they live.

Sub-tropical: The latitudinal zone between 23.5° and 34.0° in either hemisphere, bordering the tropical zone. Also can refer to vegetation, organisms, or weather typical of subtropical habitats.
