Brittle Star

micro brittle stars have saved my tank from doom. when they all migrated to the top within 1/2 an hour, I knew the change water I put in must have something wrong with it and it sure did, it was totally rotten. replaced w good water, save tank.

these animals are among the most sensitive bioindicators we have in a tank because of their motility. one can gauge changes in ammonia levels, ph, oxygen, and overall funk via these micro ophiuroides.

....and they are super cute!!

It's really fun to watch them crawling around. Whenever I add food to the tank, within a few moments pairs of tentacles start reaching out of nooks in the rocks optimistically trying to catch a snack.

I just love watching them crawl around and just be silly
