Wow... Just had a look at these guys https://www.youtube.com/watch?v=gQzMMj-CgJ4, splashing tetras. Had heard the name but never seen them and I think I may have found the newest addition to my tank as I need a top third swimmer. They are at my lfs and I'll be hopefully picking them up next month when my quarantine is empty. Hopefully I can get them to spawn. The male and female coordinate their jump out of the water to lay and fertilise eggs on overhanging leaves. They use their pectoral fins to hang on to the surface they lay their eggs on. In captivity they will sometimes lay their eggs on the lid of the tank. Enjoy the video!
