Nice tank, I love clean well organized setups like that.
I used to have a little tank in my room, but I went away on vacation and my brother "forgot" to change the filter, feed the fish, and water my several lizards/toads.
I ended up loosing all of my fish, an emerald swift lizard with BEAUTIFUL coloring that I had for a few years, a common toad I was quite attached to, and several green anoles. Only one of the Anoles died from thirst, the others died from depression. The toad dried up, he never turned his light off and it dried the entire cage out. Same with the anoles. Only one he fed was the swift, I guess when he realized he forgot to feed them he went in there, saw the green tank (left it) and the dead toad/anoles and decided that feeding the starving swift something big would keep him alive. He fed him a pink mouse, his throat could maybe handle something half that size and it ripped something internally. I have a feeling he died from an intestinal blockage/bursting.
After that, I got a few more fish, but one of them had an illness that I didn't forsee and it spread to the others.
The first group was an albino african clawed frog, two dwarf frogs, a translucent shark, and a plecko. The african frog cut himself on the artificial plant life, his intestines poked out of the wound a little bit, we tried to put them back in with no luck (he was only an inch big) but he lived for about 6 months before the shark decided to nibble on him. I loved the dwarf frogs, amazing little guys. And unlike the African frog, they don't get big and eat everything. I would have had to move him to a separate tank but they stay around an inch long. I even heard them "sing" one night.
The second group was a sword tail (after the shark died), two little things that the fish store didn't say what they were, a pair of apple snails, a freshwater pufferfish (beautiful fish, i would buy another if given the chance) an iridescent shark, and a plecko once the snails stopped cleaning as good as they did to begin with.
I want to get another setup, but on a larger scale. That tank was too small, and didn't get much attention.
I'll look around for my picture of my two little fish, maybe someone can identify.
I have a feeling the color was artificial..
