Hardest working member of your tank?

[JohnnyReeftank]

Haven't been in the hobby long and I've basically stuck to the most basic marine creatures in my reef (clownfish, cleaner shrimp etc) but I just recently bought my first yellow tang and he's been on a mission to clean my tank of algae ever since I dropped him in. I'm pumped to finally have a fish that works for his food and 'earns his keep' and I was wondering which creature in your tank has been the most functional or beneficial for your reef and why.


1) I'm liking how the tang is solving my algae issues

2) I've also really come to appreciate these featherduster-worms that shoot out a large web over everything whenever there is detritus floating around.

3) My sixline wrasse decimated my flatworm infestation

4) My Pistol shrimp is constantly stirring my sandbed and the sand looks cleaner then I've ever managed to keep it
