I have been intrigued lately by all of the symbiotic and bizarre relations ships found in the hobby. Figured I would start a thread to learn and spread knowledge.
Most commonly, clown fish! Pretty general knowledge here, but incase you didn't know. All clownfish are born male. They stay this way until they find a pair and 1 clown will mature into a female. After the change, the female will continue to grow a bit larger than the male. On a side note, the clow is not the only fish capable of do this, most Anthias for example turn from female to male. It is also interesting to note that although not required, clown fish may share a relationship with an anemone. I find a lot of people think this is mandatory where in reality, a clown will host anything, to include a rock or powerhead. The relationship between a clown and anemone is sweet due to its ability to draw in food to the anemone but also recieve food from the anemone.
Next I was thrilled to learn about the pistol shrimp and goby relationship. I personaly have a yellow watchman paired with a tiger pistol and I love to see them oporate. Both being diggers and reorganizes, they work together creating a whole runway and infrastructure under you rock work. When working at an enterence, the pistol shrimp will use its small claw and hold on to the gobys tail. If spooked, the goby flicks is tail letting the nearly blind shrimp danger is present. Aside from sharing food, this relationship is unique because the pistol shrimp will not attack the goby. It is said that for a fraction of a second, the pistol shrimps bubble shot is as hot as the sun. Amazing!
Recently I learned about an awesome little crab called the PomPom crab. This guy is about the size of an emerald crab is actualy carries around 2 anemones much like a cheerleaders pompoms. They will use these anemones not only as defense mechanisms, but also as scrub brushes to collect detrius and other foods off LR
Just a few of the ones I've been reading about. What other bizarre symbiotic relationships do you know about?
