Hello again TFF. Had an old 55 gallon tank that had been running for quite a while. It didn't have many fish, just a few small ones and the algae and moss had pretty much taken it over. I still changed most of the water weekly, but didn't do anything else to it. Decided I wanted to keep some giant Danios, but this was the only tank available, so I made some changes, just using some decorations and plants I already had. I moved the original fish to another 55 gallon tank and put in some Giant Danios. Here are the before and after photos.
