its 6" deeper front to back. If it were me I would do the 300wide out of the 240,300tall, and the 300wide. That could be because my last tank I never got to set up was 36" front to back....
That 300 tall is sitting in the back of a Silverado full size truck with a 8 foot bed.
I chose the 300 tall because I wanted a show tank. I am not keeping large fish in my tank so I did not need the depth from front to back.
I am in the process of stocking my tank with mid/upper level schooling fish and many bottom dwelling fish.
I wanted lots of color and lot's of movement in my tank and a large front panel of glass to show it all off.
Thats why I went with the tall.
If I had planned to keep larger fish, I would of went with a deeper tank.
Plan ahead and buy accordingly.
no brainer. get the 300. you might regret getting a tank 60g smaller in the end.
remember: when ever people are deciding between two tanks and one is larger than the other, when they go with the smaller size, they ALWAYS end up regretting it at some point down the road.
The first time I called them the gentleman was very helpful, and I was all set to buy an acrylic tank from them. The next time I called I asked the lady who answered to confirm the type of acrylic they use. She was affronted that I asked and told me I could take my business elsewhere. When I mentioned that another manufacturer used Lucite she told me Lucite is no longer sold which is not the case.
I'm getting mixed signals so I probably will take my business elsewhere.
