Like always its my day one in the marine aquarium hobby and aquarium store front. Always been a hobbyist but never knew would dive so deep in the trade. I too started with fresh water aquarium and my whole childhood my family kept fresh water. When i first started my first saltwater aquarium it just grew on me and i knew that had to do more to promote this hobby. I am a Post-Grad in Business Administration have worked with Coldstar Logistics, Amazon and Jindal's before jumping completely in the ocean. Other than aquarium hobby i have my interests in travel, digital games and consumer web technology.
