Good luck. My Aquatic Rescue sees many Oscars and Pacus. I rescued two 18" Pacu's three weeks ago. I have two smaller pacus here and found homes for two other large ones that came in. Have already taken in about a dozen Oscars in the last year. My purpose is to find a home for the unwanted aquatics or they stay here to live out their life. I feel very strongly about destroying fish because of whatever reason. Not their fault.
I wish you all the best in finding them a home. They could come here if I wasn't so far away.
The Oscars were picked up today. Just need to find a home for the Pacu now. Any LFS around here wouldn't have a tank big enough. If it was summer I would put him in a pond with my old albino channel cat. He survived the winter thankfully.
Thanks to Frank for getting the Oscars. Anyone for a 20" pacu? I know they aren't popular but I am strongly against destroying pets myself so lets find him a home. He only has 3 tiny Honduran Red Points for company now.
