I'm looking to make a hide for a 30 gallon tank. To be specific, I'm looking to make a multi-level hide meant to imitate something similar to a "rocky outcropping". Any suggestions? Ideally I would like it to come apart just in case. My thought was to sort of imitate Mike's rockwall he made for his Sav (foam, thinset) and to attempt to make 2 mirrored pieces that when placed in the enclosure would fit snuggly together. Opinions? My intent is to make the bottom take up a little less than 2/3 of the tank, then slope upward toward the top corner (not a perfect slope, of course). If I could make it work, I'd like to sink a ceramic pie pan into the piece as well (still removable, maybe just the lip over the edge). Any thoughts, suggestions, and questions are more than welcome. I'm trying to make a more ideal habitat for multiple Jones in one tank (though, fret not, I have back up enclosures and only the one Jones at the moment).
