hey all i need some help! i have an empty 90 gal and i'm trying to figure out what to do with it! here is so far what i have planned out. I would like to use Great Stuff on the back wall with some drift wood for the background and possibly the side walls hook up some tubes for water falls and then i'm lost. i will tell you i dont' use fake plants i like all live. and i like natural vivs i'm not useing paper towel for substrate lol or egg crate but i would like to use a small ficus "Ficus Alii"to extend over the canopy of the tank. and also how many crested (comfortably) can i put in a 90 (breeding colony wise) thanks for any advice also what plants should / shouldn't i use.. thanks a lot
