Building a 76gallon tank

[marble2388]

hello all i came across this forum and thought i should ask what everyones thoughts are on building a 76gallon tank it will be wooden with sliding plexyglassdoors. i plan on using styrafoam to build a 3d environment with one side (the cool side) having a built up floor/tunnel layers almost to the top of the tank with hides all through it and the hot side having a smaller hieght with mostly just cave like hides.

i would just like to know any thoughts on natural designs or what i need to do or cant do with what i plan. the tank will be 4ft x 2ft x 2ft
