I always forget to update this thread, hence the photo dump Was productive this weekend and bought a couple of white brute trashcans to redo my waterchange station, and added some black sand to the 90. Here's my dry aquascape. Clock is off on the lights, hence the difference in color, but I thought it was cool for photos: Lots of caves (plus one very large eel cave!) I've wanted to use this giant acro in a scape for a long time. It was upside down in my 180, but that doesn't do it justice. tall tower from my 360 build that I made even taller from the side My goal was to make it as swim-space friendly as possible with an open 'scape with lots of places to do some continuous cruising (at least as much as you can with 4' to work with). My tangs used to love racing around the turns I made in my 360 and wanted to incorporate that same feeling here (and used a lot of the same rocks!). Really wanted that feeling of a drop off tank, but also needed a nice cave system for an eel (and this one's pretty sweet) and was inspired by pics of caves with beams of light shining through. Can't tell in these pics as I have my lights sitting haphazardly on the tank, but the light comes through the back on the right side pretty well. It turned out how I pictured in my head, so that's a bonus. And I know those scratches are going to drive me nuts!
