I will admit, I go in spurts, so to speak. For a while I was collecitng frogs, and fish went on the back burner. I have been into birds for 20 years or so, but my collection hasn't changed much, since parrots are so long term. Now I am getting back in to the fish and realizing I don't have enough time to have all of the fish I would like... so, it's weird. I am trying to pick a few species to breed, and just have the rest for fun. Plus, since I live alone, I have to find a way to PAY for not only the fish but the electric, and food, and chemicals, and etc etc etc
