Mine is only 20 gallons but its big enough for decent sized fish. Have 3 liquor bottles in there, assorted little fish, a huge angelfish, two larger shiny fish (fuck if I know what type), and I had an albino shark that was probably 5" and would hang out in the necks of the liquor bottles. It died when I left town for 2 weeks (apparently it cant survive on the food tablet things) so I got 3 baby albinos now and they've already learned about the bottles.
Oh yeah, and my aquarium is in my bedroom so I get to sleep to the waterfall sound... very nice.
