Now I don’t want any slack for this… what I did was stupid. I have learned from this I guess. This fish was being sold (with two other fish) but was just marked community. I saw it and thought omg what a massively pregnant female guppy! She will be a great addition to my tank for more babies! I wonder what colors I will get. I have multiple tanks set up so if I hated what she popped out I would just move the babies over there or sell them to my local fish store. Nope. It literally was less than 12 hours she ravished my guppies and endler tank. Killing 2 and taking the tails of most of my favorites. Im sure more will die due to injury and stress. I did everything right. I quarantined, watched, and I thought did the right research. wtf is this fish?… is this not a guppy or an endler? Why was she SO aggressive? NONE of my fish are. I have introduced many fish with no issues and this was insane. She is big but I have other large guppies in there and she attacked those as well. Please help!

  1. mosquitofish are also livebearers and look very similar to guppies so it’s understandable you woud get them confused

  2. Damn, so sorry. As other have said it’s a mosquitofish. They’re really aggressive, if you decide to keep them they can live outside year round as long as the container doesn’t freeze solid. They do really well in hot summers, I’ve had them in water over 100 degrees and never bothered with aeration in the tubs.
