Professional Fish Keepers is an aquarium store owned and operated by Daniel Nestorio. Daniel Nestorio is a Marine Biologist from Portugal that came to USA in search of his american dream. I Daniel, have been in large intensive industry aquaculture in Europe, then came to USA and thinking I was going to work in aquaculture, but that company was actually an aquarium store (HERE I met my great friend Sergio from Peru)!!! So the fish was much more beautiful and there was coral...OMG I WAS IN LOVE!! from there I wanted to learn more. I went to a wholesale (big mistake but I lean some stuff) them Univerity of Miami (coral conservation lab - Aquaculture lab) for almost a year. Opened my own aquarium service company, online store. Got a job on the largest aquarium store in the world (witch was amazing until it close)... so pist off that it close, I ended opening my own store, With the help of Sergio. NOW i do things my way, i even go with Sergio to catch our own fish ;)
