I just got a 30 gal
tank myself and I'm almost done building the stand for it. I went for the 30 because it is longer than a 29.
Better put, can you think of any that wouldn't?
That's the truth there. A few months ago I was thinking about getting a 75 gal
for my africans. I read a post later on about a different type of fish and what type of tank to put it in because it needs more room to swim straight without having to make turns all the time yada, yada, yada. Long story short; I'm going to forego the 75 and the 90 and make my next large tank something that is at least 6' long.
