Why do they keep dieing?
I just bought 6 African dwarf frogs,3 phantom tetras and 2 juli corydoras and I have them in this 20 gallon long (see picture) and all of them have been doing fine untill yesterday. 3 frogs died within the span of 6 hours, and I couldn't figure out why. I did multiple test strips and the nitrate looked fine , the nitrite looked fine, the pH was good. Everything looked normal but then this morning, I wake up and another one had died. And of course it's almost 2 weeks after I bought them so the guarantee has expired. I'm going back to the store I bought the. From today and seeing if they can do anything about it and see if they can test my water. I think it might be the chlorine in the water as my city water was recently extremely high in chlorine but I also think it is the ammonia levels due to the high waste level from the frogs. If you have any tips or what I should do please let me know as I am 14 and new to this.
