    the lake behind my house hadnt sustained life in it for years before not even plant life. this year magicly the lake came back to its former self plants grew in and now the lake is over populated with these fish can anyone id them for me i dont know how they got in or populated so fast i go down to the lake every summer to check the water and it was always poisened now its fine. but there are millions of these small schooling fish schools of at least 20 fish each and the schools never change members or combine they are like sub cultures.

    Are those livebearers? It looks like it.
    I have ones that live down here that look alot like those. Idk the names of them but they are in harsh waters down here also. I'm thinking these guys are very hardy and can handle bad water pretty well. Hmm ???

    Gambusia, I used to have a tank of them. They are livebearers. The females are larger than the males.

    i had a few of those from a lake where i live because my frog tank had mosquito larva. They are like a plain guppy. they come from the same family and they are called mosquito fish if not speaking scientifically. Careful though, if you choose to keep them they are aggressive and even more so when they are with a group. the more there are of them the more aggressive they become. they wont kill each other though. i saw them attack a large blue gill that could eat them whole. the entire group chased it off. they also get black stripes under their eyes when something is going on. generally when they are stressed or excited. i hope this helps.
