Hi all. I just wanted to ask ,does anyone Have any advice or like opinions if i should get a glass Aquarium(7footx2.8footx2.8foot) but it could take 3-4months(And my Arowana is pushing 20'') Or will i get a 7ftx3ftx3ft acrylic and i could get that in about 2weeks. Is acrylic as nice as glass? Thanks in advance for any info
