Hi my name is Nickle and I am new to fish keeping. I have three tanks a 5,10,and 29 gallon. I have guppies, tetras, glofish, and corydoras. I have also had an long first month of getting started. all three of my tanks have high ammonia levels, and my fish and plants keep dying....:-( the place where I bought my tanks(2 of them) and all my plants and fish is doing a great job of helping but I am still dissapointed because I do not have any healthy tanks. any advice is welcome. feel free to ask for any info I did not include as I am new to this.
