broke down and bought a fresh setup

[kuatto]

After pomising my better half she could have an archer fish,we finally bought one of those cube terrariums(18 x 18 x 24) with the screen tops,front access doors and fake rock walls.Have it looking pretty nice with logs and fake plants,everything is ready to go just need fish and maybe a fire-bellied toad.
I was reading up on the archer fish and some say they are brackish,while others say they would be fine in just fresh. Anyone have any experience with these interesting critters? The water would be 9" deep with viewing from 3 sides.
