Alright it is getting about that time for me to start looking at a bigger tank for my Oscars. I am thinking going with Dimensions of 4ftX4ftX3ft = about 270g. What size glass(thickness) should i use, and is that a good size even. I was thinking about getting them a few tankmates besides the Silvertips and the pleco. I am thinking Arowana but am lost on everything else. But i really need info on if that tank size is good, thickness of glass, and what type of filtration i would need. Thanks alot for all your input, and i should have pics up shortly of all the tanks.
