You can see how the background and rocks have matured. I think the light coating of algae/diatoms adds realism.
I unfortunately lost a bunch of the fish due a heat wave last summer when I was out of town. So I ended up scrapping the tanganyikan theme and now have a random mishmash of interesting fish. There's a lot of personality in this tank and it's pretty fun to watch. The Aplocheilus Lineatus (golden wonder killies) in particular are some seriously under-appreciated mini-monsters.
Hi! I've just dropped by to see your work, it's amazing really!
BTW may I borrow some of your ideas for my future work(s)? Haha (s) really included, I may set up a 3d backgrounds that's quite the same with what you've done, not specifically the design but the idea. Thanks! Oh yeah, could you post a pic/vid for some updates regarding the setup? Wanna see more out of it.
