I only have three fish in my tank at present.  Fish impose a larger biological "load" on a tank than do corals and anemones, primarily because the latter do some photosyntheis, which aids in the recycling of nutrients.  I only have herbivores right now, which load the tank less than carnivores (as well as removing algae and requiring less feeding [I'm lazy at heart]).

Maroon Clown Fish

Here is the Maroon Clown FIsh. He's tough to photograph because he's small and fast.  He lives absolutely all of the time inside the Pacific Long Tentacled Anemone: when that anemone gets small, he becomes frantic as his "house" shrinks under him.

Blue Spotted Goby

Here is my tiny Blue Spotted Goby.  Or maybe he's a Yellow Goby (even though he's green). No one is sure.

Gobys gobble up sand, chew the algae off of it, and then spit the cleaned sand out.  He is pretty skittish, and scoots into small caves if you approach too quickly.

This one has a perpetual frown on his mug. 

I decided that I needed another, larger Goby to help sift the sand.  When I introduced that Goby, my little one puffed himself up so that he could defend the cave he had chosen as home.  Here he is being fierce.

Watchman Goby

Here is the new (and relatively huge) Watchman Goby.  He is placid and wonderfully camaflaged.

I introduced this Turtle Weed (a form of macro-algae) and within a day or so, I discovered Mr. Watchman reclining in luxury on a bed of the weed (which he also nibbles on periodically).  Very cute!  Photo by Stacey.


Goby's lack a swim bladder, and thus must either swim or sit on the bottom: they cannot hang in the middle of the tank effortlessly, as can some other fish. Thus, the Gobys often are to be found perching cutely on something. Here it is an algae infested rock.

Here, the Yellow Goby rests on a Green Moon Coral.

And here are the Goby Brothers, resting in apparant tranquility.
