Nice fish, 8D.
I got another Barra the other day, and put it in my tank with my 2 bigger Barras and my silver perch. The silver perch has taken to chasing the new Barra around, to the point where the Barra nearly carks it from being tired. I moved the new Barra into another tank til he grows bigger, I was about to move the perch, but I don't want to wreck the schooling the 2 barras and the perch have established with each other.
But this new Barra is a dud I believe, lol. The poor bugger, he eats feeders and evreyting, but he is almost always, and I'm not overreacting, but he is always resting on the bottom, the others always at least make the effort to float on the spot, lol.
