I have been waiting to post on this thread since I got my BSJ over a year ago(close to 2 now), and I am happy to report my Spock is still with me thriving. He is the most awesome fish, and surprisingly super easy to care for, since he has the right set up. He is the only fish in an Innovative Marine 38 tank. He has about a 5ish inch sand bed with ton of rubble, and a handful of larger pieces of rock to build tunnels around. The average tank temp is about 75 degrees, but I don't have a chiller or anything. It's in our master bedroom, and we keep that a good deal cooler than the rest of the house. He eats all types of frozen food and flakes, but doesn't like pellets.
I never thought I'd be ok with having a whole tank for one fish, but bsj are so interesting with cool personalities, that I am 100% ok with it. I have tried to house a pair of firefish (from dd) with him, but I think eventually, the firefish just got too stressed out by the bsj and they didn't make it. That was the first and only time I tried out tankmates for him. If you're willing to put the work into the set up and a completely jump proof lid) these fish are so worth it.
