Grew up in PR where I would work weekends and after school in a freshwater aquarium store. Thatís were I learned a lot in my teens. That was over 30 yrs ago. Had Japanese Ryukin goldfish with the long fan tails, Oscar, angels, red belly piranhas, arowana,cichlids in about 7 tanks.
Now Iíve decided to start up an old 55 gallon tank. Loving the new technology with led lights.
