I was in the process of figuring out which size tank I want to upgrade to. My current tank is a 180gallon (6x2x2ft) tank which is built into the wall. This being said I was looking at the 270-280 gallon tanks that are 6x3wx2 tall..is this enough swimming space for them? I would convert the 180 display tank into a sump so the overall volume would be around 400 gallons. The max length that I could use in the space the tank is in would be an 8ft tank. And if I am going to have to take the wall apart then I could do a 8x3x3 tank which is 540 gallons again using the 180 as a sump I would put this setup at 700 gallons. I know its my decision to make financially but I was wondering from the experts here whether a 6x3x2 is enough space or should I just plan for the 8x3x3? Which if the 8x3x3 is the answer then can that also handle a Tem for life? Stock for like would be Two orinos One mono Maybe one TEM and two 11in plus oscars. Thanks for the help guys
