I am new to this forum. I am glad that I have found it, I hope to get answers to my questions here. I have 20 gal tank, I got it as a kit from Petco. I am trying to grow plants there and lost so many fish already since I started this tank about two years ago. Some fish lived for as long as 6 months, and other just for a month or two. I had two or three ich spikes. Dwarf gourami is the only one left at this time, after last treatment for ich. And I am proud of my Amazon Sword - it likes my tank
