I’ve kept this slug in a 24-gallon reef tank for six months. It’s peaceful and doesn’t interfere with other corals. Only suitable for experienced aquarists, but once established, it’s a stable addition to the tank.

The slug is active and stays in one area without causing issues. I had to maintain stable water parameters, which is expected for expert-level care. It’s a good choice for a reef setup with proper conditions.

After some time, the Bornella calcarata settled in well. It’s not flashy, but it’s reliable and doesn’t damage corals. I appreciate the clarity in the care requirements—this helps avoid mistakes.
