So. Here I am looking for hopefully the best advice to keep my fish alive. I'm Ashley. I live in Chicago and I have a 10 tank with only one guppy. I did not know about cycling before I bought 5 fish. I added them and then one by one they died
I cried and felt devastated. I added tetra startup (with Bio Spira). However, one guppy is still alive. We have had the tank a little over a week. The guppy however has kind of a black end. It seems as if he has ammonia poisoning? My snail was dead in the tank for 4 days. I thought he was hiding. I am not sure if this has caused the higher levels. I did a 10% water change yesterday. I am not sure what I should do?? Please help and give any advice. Here are my readings.
nitrate 20 ppm
nitrite 0 ppm
ammonia it just says near danger zone
