Hi everyone, we are new to the hobby of fish keeping.

Just got ourselves a 90L tank last week, and we kinda just jumped into it without researching or anything, our local pet store were not very helpful, i think they just wanted to make as many sales as possible. So we ended up with over 30 fish. So, over the last week we have lost about 30% of our little fishy friends, and I am starting to get a bit worried about it all. I had a bit of a read of the E-Book provided by this site, and i believe i did not cycle our tank properly. So I have just gotten myself a ammonia test kit, but no ammonia levels were detected??? so I am kinda stumped on how our fish are dying???
