My Blua Acaras tank

This is my newest tank. Got it for $400 bucks for a new never used 125gal tank, homemade stand, two 3ft T8 lights, glass lids. It is home to my Blue Acaras, Serpae tetras and Leopard corys,both and Roseline sharks. It's only been set up for two weeks now. I had 4 Blue Acaras, but two didn't make it so far.
