Hi. Found some fish in a tank but none of the tags had anything to do with rainbow fish. They are still young so I'm not sure what kind they are. Guessing either celebes or pseudomugil. It was 50% off night so got 6 for $20. Sorry about the crapppy iphone pics.
There is 2 or 3 that have pointy dorsal fins so I'm assuming they are male. Will take a pic in a few weeks if the colour up by then. Randomly searching google; "Pseudomugil sp Red Neon" looks the most like them at the moment.
