After going through some of the threads about sea cucumbers, I found out that they were pretty useless in the tank but are aesthetically pleasing to look at. Well way back before reading any threads I had already purchase a yellow sea cucumber. Its been in my tank for about 3 months now and something amazing happened to it. About 2 days ago it divided itself into 2. ??? The original 1" dude I have now has a 1/4 inch clone!!! Is this how they reproduce? If so should I worry about it multiplying again? I've read that these timid creatures are bad-ass dudes in releasing toxins that could do alot of damage to other livestock.....and now i've got 2 bad-ass cukes. Though I am amazed.
