Thanks! It has 1 Siamese Algae Eater, 7 Harlequin Rasboras, 5 female guppies, 4 glass catfish, 2 Diamond Tetras (the others died from a faulty heater that burned them), and 2 Kuhli loaches. There are also a fair number of juvenile guppies in there too.
I have had this tank set up right at a year. We moved during that time, and I actually took most of the water out to about 2 inches, left the fish in there, and drove them strapped to a trailer in 117-degree weather (broke all the Oklahoma records that day; our street lights were literally melting) and only lost 1 neon.
I think the plants help keep it clean, but that being said, I have to change the water regularly because the plants don't ever do great in my tanks (I'm not an expert on nutrients, etc.) and they lose leaves.
EDITED TO ADD: I just looked at the picture, and it's an old one back when I had the neons in there (they're in my 55 now) and my dwarf gourami was still alive. I guess I should update my photo! Here's a link to the album of my 29 on a different page. http://www.tropicalfishkeeping.com/m...abitants-5017/
