Seriously, fish keeping is one of my favorite hobbies.  I have a 55 gallon "benthic zone" reef tank, a 20 gallon planted waterfall paludarium, a "blackwater" planted tank, and a small outdoor pond.  My main fish keeping interests include making my own equipment, planted tanks, and unusual fish stuff.

How about taking a look at some of my tank stats: (pictures to be added later?)

55 "benthic" reef:
This tank is a 55 gallon tank that houses a yellow tang and a flame hawk fish, along with an assortment of live inverts.  Because this reef is modeled off the benthic zone, there are no corals, and the lighting is low.  Coraline algae, feather dusters, and other small, non-light-loving inverts are allowed to "do as they please".  I encourage the coraline algae and the feather dusters, everyone else has to fend for themselves!

I am still mourning the loss of my cinnamon clown fish.  This is the first fish I have ever had that I can be reasonably sure died of old age.  I kept the little guy for four years, and I know for a fact that he was kept by another fellow fish keeper for at least two more years before that.  This fish had a personality like few others.  I will be replacing him soon!

This tank has an external sump style biological filter with a "sea-clone" protein skimmer and a MASSIVE Iwaki pump.  I am not very happy with the sea-clone.  The skimmer that I designed and built myself worked better, but cost more to run (required wooden air stones).  Oh, well.

20 waterfall paludarium:
I had a lot of help from my friends in constructing this tank.  It has a "high" side and a "low" side, separated by a Plexiglas plate which has a waterfall running down it.  This tank was designed as a novelty, and is one of my favorite tanks.  Water is pumped from the low side to the high side by an old powerhead, and then filters down the waterfall back to the low side.  I have re-worked this tank a number of times.  One of the changes I made was to plant the whole tank.  I used Flourite substrate, and planted with Anubias species, Swordplatns, Nomaphylia hygro, and some random stem plant that I got free in a bag of fish.  I am kinda proud of that last one.  Only about 1/2" of it was floating in the bottom of the bag of fish, I was careful, and now there is over a foot of it in three or four different bunches!

Anyway, this tank houses gold barbs, a black molly, and a sunset variatus (the two live bearers are on the high side, the barbs are on the low side).  A surprising problem I ran into with this tank is the tendency of fish to work day and night to climb up the waterfall!  I tried a number of different fish before I found some that didn't try to kill themselves by climbing!  A small sponge is used to keep a sleepy fish from getting sucked over the lip of the fall <imagine a fish screaming here>.

I use the plants for most of the filtration on this tank.  I have a "mini" size bio wheel for mechanical filtration (the wheel was taken off to allow the plants to get more ammonia), and the waterfall sponge does some mechanical filtration.  The lighting includes two tubes...one 20W and one 15W fluorescent "plant grow" tubes.  The spectrum isn't great, but the bulbs were on clearance sale for dirt cheap!

15 gallon blackwater:
My blackwater 15 is a wonderful tank.  Low maintenance and striking looks are combined with interesting fish to make a well balanced tank.  A centerpiece of driftwood is accented by java fern, java moss, and anubias nana, which are all growing on the wood.  There are other stands of these plants on the sides on the tank, but they are temporary (just needed some extra room for plants!).  I have two albino plecostamus and eight giant danios in this tank.  Giant danios are by no means the best looking fish going, but they are VERY active (I would call them manic), and they have a nice irredecent shine to them.  The plecos spend most of their day hiding, but when they come out, they have quite a striking color pattern to them!

This tank is filtered by a Bio-whell 110.  No extras.  I do remove the carbon from the filter cartridges to leave the water nice and tannic and dark!  When I get around to it, I boil some oak leaves and pour the "oak tea" in to darken up the water.  This adds a great effect if you like blackwater or tannic tanks.  It also keeps the pH a bit lower and adds some good ole "natural stuff" to the water.
