I really like the aesthetics and footprint of cube aquariums, and I am really thinking of doing a largish cube as my next tank. I have some questions and concerns though. Keep in mind I am speaking about a cube of at least 100 gallons that has sides of 30 inches. How do fish who need large tanks for swimming room (tangs etc) do in cubes? How difficult/feasible is it to have the overflow in the middle of the tank with live rock covering it? What are some specific challenges with larger cubes that I should be aware of.
Thanks Crabs for heads up. They actually do well. Do however keep in mind Max Size potential (as you will not want a dussomieri, vaglimi,tang, etc who can grow to over a foot). I limit to dwarf angels, tangs such as yellow, kole eye, wrasses, clownfish and gobies who will grow in tank but not outgrow if that makes sense.
Center overflow should work and disadvantages are swimming length as a 93 cube will be 30 inches, a 150 will be 42", etc but overall depending on scape, there is adequate room to keep fish happy.
I currently have flame angel, yellow tang, lg engineer goby, three firefish, 4 clownfish, purple basslet, diamondback goby, butterfly and lawnmower blenny in my 93g cube
I have ghost aquaX overflows (one in each corner) which consume NO space and almost un-noticeable) that flow into a Skimz model 22 sump
