Do you know the saying " life finds a way " well I've got a prime example in my marine tank. After removing all of my fish and i thought all the crabs as well and making it a live rock tank only ( figuring it wouldn't need as much care) . I have found a plethora (oooo i know a fancy word haha ) of new life in my tank, I have found so far 3 different species of crab, a kind of shrimp( I only got a glimps of it), a little bristle star, anenomes, snails, Christmas tree worms, oysters, mussels, a few different types of fan worms and probably lots of other little creatures that I haven't seen yet.
It is amazing that these have appeared out of nowhere and is surviving with only minimal care.
I am wondering if anyone else has had any experiences of this sort of thing?
