The fish that we collected on the trip to Peru arrived yesterday. We got a couple dozen killifish, Laimosemion (Ruvulus) rectocaudatus, that we found in the ditch along side the road. The little run is water was lousy with these killies. We could have collected hundreds of them. The fish is pretty and mean, and also good jumpers. I put them into a 20-gallon tank with only a few inches of water to acclimate them. They were spread out a day after this video was shot, but I noticed that they were doing their best to jump out of the tank, and grabbed the video camera… Enjoy.
