Together

Here, in captivity, two seemingly unrelated creatures have come together to live and provide for each other. The fish, a Lawnmower blenny, uses the clam (Tridacna derasa; aquacultured) as a perch to overlook the aquarium and keep an eye out for the non-existant predators. In return, the blenny chases off any fish that get near the clam, allowing the clam to remain completely open, without disturbance, during the 12 hour photoperiod and perform photosynthesis for a maximum amount of time.

I have witnessed my female clownfish lately taking interest in the clam. She is gravid and is likely hoping to use the clan as a home, similar to the blenny. However, the blenny hasn't been too happy with this, and the two have gone through many quarrels lately. I'm working on getting a picture of the clownfish laying in the clam, albeit, it does not lay in the clam for long because of the ever-oppressive blenny.
