I've had one for about 5 months now. I have a 30WX30LX16H (63 gallon) with a 20 gallon sump. He shares the tank with a flame angel, coral beauty, two occelaris clowns, a yellowtail damsel and a royal gramma.
In the winter, my tank stayed about 76 degrees, but now it fluctuates up to 82 degrees. "Steve" the BSJ does scrape himself occasionally, which clears up after a week or two on its own. He got a bit of fuzzy mouth, whatever that was, which also cleared up. My BSJ is definitely high-strung, but being the biggest fish in the tank really helps. He eats everything. Pellets, wafers, spirulina flkes, misis, it goes in the water, he eats it.
Advice:
- I have fine aragonite and crushed coral mixed, mine seems to really like that for building
- Ensure that there are rocks to tunnel under that are supported by other, smaller rocks
- feed a variety of foods
- Do not mess with their dens/homes
- Have a lid; mine goes bonkers once a day at least
- Keep good water, mine seems to heal injuries on his own
- Let him be the biggest fish, he already stresses about what's going on
Good luck! I'd also like to hear more advice!
