Biodiversity

I get it bad from my family. I use a pair of binoculars that were made to watch butterflies so the focus range is very close. Really great for scanning all the nooks and crannies in my tank. But my background is a "mud biologist", so I am used to seeing the world thru a microscope.

Ohhhh what a great idea!
I am a constant figure at my tank at night, If I could just catch the cardinal fish letting out fry I would be happier but all in good time I suppose.
 
Fun thread to stumble on. The critters are one of my favorite things to watch. There's a whole different world to look at when I lay on the ground at night right up against my tank, or, during the day, when I look under the frag rack, and see the thousands of copepods crusing around, and the amphipods chowing on them. The bristle worms I can do without cause they sting me all the time but....
 
I think I spend more time looking at the micro life in my tank than the fish and corals. I spend hours going over my tank with a flashlight at night. I just noticed my feather dusters have been spawning like mad and are taking over my overflow.

I remember years ago a guy at the LFS talked about his live rock tank. He kept a tank just for live rock, swapping out pieces here and there just to see what showed up! When I re-aquascaped last month, I traded a couple pieces to the LFS for some new cool ones just to see what kind of life I get, good or bad! So much more exciting that just putting a pretty coral in and letting it grow. The coral and fish are just to trick everyone else into thinking im Sane.
 
Here is a picture of the inside of my "in tank" surface skimmer. I don't have a sump and this thing skims the surface to remove the thin film that accumulates there. It also functions as a overflow as It feeds my HOB protein skimmer.

This is a view from inside after I removed the bottom. It is almost completely filled with tube worms and amphipods. The tube worms grow from the sides and go all the way to the center almost stopping the water flow. These tube worms I would imagine are a very effective filter and water purification plant. I am not sure what they would remove but I imagine they feed on any microscope life including bacteria. In this picture, much of it looks like wet cement, thats because I had to break a lot of them to allow more water to flow.
I love this stuff.

This is the unit from the side. I don't remember how old it is but I guess it has been there for 12 or 15 years.

Hope in many years my overflow looks like that! I just got a basket of shells from my LFS. Full of mysids, pods, worms, and whatnot to work on rebuilding my pod population. Since I dont have to opportunity to collect nice mud from the ocean here in the mountains of northern California! I keep forgetting there is fish in my tank to look at! Of course when I walk in the woods, I dont even see the deer....im to busy looking at some cool spider thats only 1/4" across on the underside of a mushroom.
