Richer thanks! That's the info I was looking for. I was considering going 3 feet wide since I can't really fit an 8 foot long tank anywhere in my house and I could get more area for them with less wall space. I'm also planning to go with 16-18" deep so I can use the less expensive 1/4" plate glass and also because I have a 55gal that's 2' tall and I hate cleaning it, what a pain
Instead of adding any more of the large monster fish, I had thought about adding a school of maybe 8-12 small, colorful, active, top swimming fish. Maybe some kind of tetra? As far as I know, the balas or loaches shouldn't give even small fish any problems, but that may not be the case when they start getting really large.
Jamison we'll be building a plywood tank based on the plans from GARF
http://www.garf.org/ I suppose I should have specified that. IF I can find a place to build me a custom glass or acrylic tank the size I want for anywhere near what it will cost us to build the plywood one, I will consider that option. So far though all the places I have priced are considerably higher. I don't really have a materials cost yet because I haven't decided for certain the dimensions, but I'll be happy to post them once I get it together.
Richer, do you think if I went 5' long, 3' wide and 18" deep that would be sufficient? Works out to nearly 170 gallons. That would fit best in my house at least, but I could probably squeeze out room for a 6' long if it were absolutely necessary (yeah I know bigger is always better hehe)
