Hi everyone, my 20 gallon high finished cycling two days ago and I think I have my finished product! I do have some grass coming in the mail today that I am going to try to hide the tubes from the air pump with, but I love how it has come together for my first tank ever! Right now I have 7 danios in there, and am looking to add 6 or 7 cories with two honey gouramis to round this out. Any suggestions for my tank, and is that stock okay? Thanks for your time!
