First off let me say how much I appreciate this forum. You have helped me set up my aquarium which i thoroughly enjoy. Without the help of this forum it would have been much more difficult to select plants, fish types, etc, and I would have probably accidentally hurt some fish :(.
My tank has had fish in it now for a couple months, and I have never had any NH3 or NO2 and only one fish death (a bullied Gourami).
I have a 20 gallon tank with the following:
3 dwarf Gouramis
5 neon tetra
3 plants, a very large one that covers half of the back, and two smaller ones
I would love to add 3 more hatchetfish, 5 more neons and a couple more cories, but I fear this may result in overstocking. I would love your thoughts.
I am wondering how often and how much water I should change. I have been changing the water very infrequently (5% each month) because I test the Nitrate and it has never gone over 10 ppm. My understanding is that this is ok, but I have been told by others that the fish poo that accumulates in the bottom can be harmful, and that I should change it more. What do you think about this?
Thanks for your help!
