ook dit heb ik er over gevonden:
I am pretty new to the Molly thing, but have spent alot of time observing them and reading about them. There appears to be only three species of them: P. sphenops, P. latipinna, and P. velifera. Lyretails can appear in all three species, and the various colors like dalmatian, marble, gold dust, etc. can also occur in all three species. These fish like warmer temps, 25-27°C, and are definitely brackish water fish. Suggested amount of salt varies from a teaspoon to a tablespoon per 40 liters. I try to achieve somewhere in-between for my setup. These fish live up to a couple of years in freshwater, but can live as long as four years in brackish or salt water. Some hobbyists have added them to their reef tanks with no trouble and report that they keep hair algae and caulerpa in check. I have a 100 liter brackish setup with 3 gold dust sailfins and 2 marble sailfins. I expected the two males to fight, but they hardly notice each other. Amazingly, the respective colors seem to only want to mate with their kind. The marble male will nibble on my finger. They all gather at the front to look for me at feeding time. The largest gold dust female just had babies. I think there are 20 or so. They are all different colors, probably because she was in a tank with other colored males at the pet store. Anyways, these are my favorite fish, and definitely worth time and effort to keep.
