Glass vs acrylic for monster tanks?

[Elyse]

So I plan on having some custom monster tanks made in the future...likely a 200-250 and a 300. 

First question, which would make more sense... discus or south american chichlids in the larger tank. 

Second question, i've heard Corey talk about how beyond a certain point he recommends doing acrylic vs glass for the larger tanks. Why is this...is it stronger?

@Elyse Douglas It’s a personal choice. I’ve never been much of a discus guy, but I adore larger fish, so that’s the route I’d go. Personally in a 300, I’d probably go with a school of 12 albino Geophagus Pyrocephalus, an Oscar, an L014 pleco, and probably an ornate bichir. However, you keep whatever makes you happy. Also Cory has said, after the 125 mark, he shoots for acrylic because it is lighter to move, and is a bit stronger. The only issue is it is much more expensive. If cost isn’t an issue, I’d go acrylic with everything. Good luck!

Weight and I believe acrylic offers better clarity as the glass on monster tanks needs to be quite thick. 

On weight, a 180 glass weighs 340# which will be a struggle for 2 people to move. An acrylic comes in at ~160#.
