Hi - I'm new to AA - been out of the hobby since my teen years (retired now) but I love animals and this will fit nicely with the other critters in my home. I don't have any equipment so I need pointers; thought about buying used tanks and filters (so I can get several going with least expense). Presently searching for a good place to buy fish. I'm really excited about starting again and see this forum as a great "life net" to avoid all the mistakes I made many years ago.
