Hi! Am I doing this in the right place? lol.
My name is Rebbecca, i'm 13 and I got a 62 litre fish tank yesterday. Basicly, I want to do everything right lol

.
I already have 3 plants in, and I have also got some snails that came with them. My dad has put some oyster shell for the water and a little bit of fish food in for bacteria. Here it is

:
We have a 30 litre Bi-orb downstairs that we have had for a while, we have one neon tetra, 2 other tetras, 3 other tetras, 3 guppys, and one female fighter fish. I found one of the guppys dead this morn, we only got the Fighter yesterday, does anyone think that it has anything to do with the fighter?
All answers are appreciated
