Just found this site. Got interested cause I want to do a abyss tank. My salt water experience is limited, text book knowledge, have not been doing it long enough to have the experience knowledge. The only oddities, cow fish and anglers. I have a 5000 gallon autimated pond with show koi, four salt tanks, frag tank, 2 brakish, 3 tropical and two cold water fresh at the moment. Cold water fresh being my strong point. Look foward to using the site. Have a great day!
