Hi I just joined. I started my aquarium about 7 mos ago. I have a 20 gal and I am about to move up to a 55 gal. I have a very large fish that I have yet to identify, 2 albino cichlids, a jack dempsey, a butter peco some catfish and a baby silver arowana separate tank. I hoping this forum will assist me in managing and caring for my fish.
