Haha, he was definitely interested in everything, always is! Oh yeah, all three of my dogs get regular nail maintenance! Although it's been much easier since the move. There's no grass, so everything they walk on is hard, like rock, cement, kool decking, it all helps keep their nails short.
I'd probably go for the elbow if I were you, but that's just personal choice!
I got the filter installed, I haven't figured out the end layout of the system. I want to play with a few different options. Overall, I like how the tank is looking. Most everything is growing well. I've gotta figure out something different for the back left side of the tank, next to the Anubias covered driftwood. I've got a couple marbled queen radican swords there that seem to want to stay low to the substrate. I don't think they like the low tech environment. I think I will pull them out and stick them in an emersed tank and find something else for that spot. There is also a C. affinis "Metallic Red" growing right in front of the swords. I think it was being shaded too much by the larger swords when I first planted the tank. I recently trimmed the sword leaves back some and the affinis has started growing more. I would like something in that spot that will grow taller but also add another color to the sea of greens. I'm probably going to take a look through my Cryptocoryne collection and see if there is anything that would work well to fill the spot, if not I will look around. If I do go with a Crypt I want something with a little different color and texture than the other plants in the area, probably something with heavily bullated leaves. I've not already got anything specific in mind. The right side of the tank has a nice patch of C. nurii that has been doing well. It's starting to get a little bigger. There is also, at the base of the right end of the driftwood, two Red Tiger Lotus plants. They are still fairly small but I doubt that will last a whole lot longer. When these plants get larger the tank won't seem like such a sea of green, which has been kind of bugging me lately. lol.
Here's a picture I took last night. It's overexposed but it's the best I've been able to do so far with my iPhone. I spoke to my dad this morning, who has been a hobbyist photographer for 40+ years(I grew up with a dark room set up in the bedroom next to mine!) he is going to help me get some better shots of the tank tonight. We will bust out the tripod and a real camera and see what we can do. Might try for some shots of the 20L too!
