otolith - yeah it is "my sized" 90'ish gallon. i wanted 48L and 24" wide..so it's like a 120 but shorter

i don't believe that i abuse my equipment. i feel i keep my stuff in order pretty well. i think i would be EXTRA careful w/ an acrylic tank...but i'm sure that is what everyone says though
i'm not a big fan of the center brace either. ALL of my tanks (excluding the 55gal) have been open top (5ga, 10ga, 20gal, 58gal)..but i really don't think it will be that big of an issue. would be nice i have something to attach my front CL ports through

i'll only ever use a cleaning magnet so reaching around shouldn't be an issue...never really do that now...except when i siphon the sand
melev - well i will be moving out of this apt into a house...where i'm SURE we will stay put for 5-10yrs at the minimum. i'm not worried about the weight of moving the tank...more of the breaking it or it blowing a seam
arconom - 120 is only 4" taller...not an important issue for me. i like shorter tanks. my 58 is 20" and i love it. i would like to keep this tank as small as possible w/ 4ft in length...and i wanted 24" of depth. i'm thinking smaller is better to move and easier at the moment until i get set up in a house SOMEDAY
well my wife is putting the brakes on an upgrade after she heard that she couldnt' prolly put a yellow tang in there

this is the main reason she wants to upgrade...to add more fish and ones that SHE likes. we will see what happens i guess

on the bright side it would save me a LOT of work and decisions
