Here's my submission:
Water is not so clear in first pic, just after Mysis feeding time

OK, here's what's in the tank...
4 Clown Loaches (1 inch at most, just added a week ago)
1 Male Convict (3-4 inches)
1 Red Belly Piranha (2 inches)
1 Red Finned Cigar Shark (aka Sultan Fish, Mad Barb etc etc) (7 inches)
2 Common Pleco's (3 inches)
1 Blue Gourami (4 inches)
Heavily planted at this time, and lots of filtration and circulation. Dimensions are 36*18*16
I have a few other tanks ready for anyone who needs to be moved. This tank is in my room so I can keep an eye on any problems. The temp is usually a little higher than 25, and I use metal halide lighting.
The only tank-mate that had to be moved was a smaller Gourami who was getting nipped non stop by the piranha. Now that he's gone, there have been no problems for 2 months.
