lol, no blind cave fish. You're probably looking at a Giant Danio ( fillers until I get on hands on some Leptosomas ). Tank is 75 gallons. There are 5 or 6 huge boulders laid out on top of eggcrate. Rocks were stacked on top of that base. Most of the rockwork is coral collected locally along with locally collected driftwood. The rock is really craggly and fits together like a puzzle. No shimmying at all. Cost me a few afternoons running around the woods to find the rock-work. Take a look at the rockwork in my old 55 in my profile. I was constantly worried about that slate falling over. Holey rock or coral fit together better.
