What kind of fish do I have?

I recently inherited a 70 gallon aquarium from my mother. She was a science teacher and had been given various fish from students and collected some from the wild, so being a newbie I have no idea what they are.

I'd gladly look them up myself, but the only website I could find was just for fish native to Australia.

Below is a quick snapshot of the tank and some of the fish:


There's also one very nifty looking fish, but it likes hanging out underneath a rock and I haven't been able to get a good shot of it yet. Below are two bad ones...I'd be impressed if someone's able to identify it from them.

Wow, thanks! This morning when I fed them I got a better picture of the last fish.

Yay!

I'm pretty pleased. I've cycled the tank and added five Tiger Barbs (puntius tetrazona) and five Blue Flame Tetra (hyphessobrycon columbianus) as well as a few Pakistani Loach (botia almorhae).

I also added a Whisper 60 (200W) heater and a Emperor 400 power filter. Here's a new pic.

Actually, I just had my first fish die and it was a tiger barb! He wasn't torn up or anything...just laying belly up in a plant.

I watched them and didn't see any harassment at all, but that was with the light on. *shrug*
