I like those barbs, also, that tank looks very natural, I recently went to a lake, and it looked almost exactly the same to what you have set up. I've also had the same thing happen to me with the MTS, I didn't add enough sand, and eventually the filter flow upturned a bunch of soil and made it all cloudy.
Thanks, that's kind of what I was going for. I have snorkled in lakes and liked the style of scenery underwater.
But also I want to have a nice professional aquascape... One that will win me a title in an international aquascaping contest. I've got my eyes set on AGA 2011. Or maybe if I can get it good enough, 2010. My camera skills aren't the best though. I'll bump this with nice photos in a week or two.
