Out of curiousity I decided to put my GoPro session in my 55 gallon tank to see how things look from within. The first time I held it and the fish were all energetic as I was standing by the tank. The second time I left the camera in the tank as I went to mix them food. However they stayed hyper. They knew I grabbed the plastic cups I use to thaw and mix frozen food from off their tank which means they are getting meat not flake. Note the babies, the larger ones look like smaller adults with a definate dace looks (my impression is chubby, blunt nosed, longnose dace. which sounds like an eastern blacknose, not sure if snouts are grown into). Their are also a couple very tiny babies who appeared a few weeks later that you can barely make out at the top of the tank.
