The brown sea hare arrived healthy and stayed active in my 100-gallon tank. I cleaned the tank after it released ink once, and no other fish were affected. It’s a unique addition to a marine setup.

I noticed it released ink once after a few weeks. I followed the instructions and cleaned the tank right away. It’s a fascinating creature, though requires careful tank management.

The sea hare is active and looks beautiful. I had to be cautious about tank cleaning after ink release. It’s not ideal for mixed-species tanks.
