Ran across the board thru youtube so I thought I would join looks like a cool site ! I have 2 50 gallon tanks first one has a couple of red ear sliders that I have had for a year + with a fluval 404 filtering it. I chose to have all natural back ground as in the gravel and rock ledges for them to bask on and stuff. The other tank has 3 oscars and a red belly pacu and a standard pleco.
