This morning, my parents told me how they're going to move the living room stuff around and that's where my fish tank was. When I got hom at 4:20 from school, I see the fish tank in the dining room. I look inside and there is my Bala Shark, nose down into the gravel and 1 Black Tetra on the gravel on its side. There was also another Black Tetra on the other side and I was so pissed and I closed the light in the tank and that one tetra started moving, but he was looking up. He was gonna die. I couldn't do anything for him.
My mom told me that they died from shock of moving and that there were no bubbles to give them oxygen. The only good coming out of this is that I can get new fish that will peacefully live in my tank. I now understand fish and hopefully, I'll get some nice fish. Can you recommend some fish of different variety's? I want it to be a community tank with species from each family. I don't really want Cichlids now though cause I want a lot of colorful and small fish instead of one big one with a lot of color.
Thanks!

Thanks!
