Like always it's my day one in the hobby. Always been a hobbyist but never knew would dive so deep in the hobby. I too started with a freshwater aquarium. When I first started saltwater aquarium it just grew on me and I knew that had to do more in 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.
