Welcome to R2R Koshi. I was in Alaska exactly two years ago this week. Never made it to Anchorage, but did visit the aquarium/salmon hachery in Juneau and was surprised to see the diversity of life in the waters off Alaska. Some stuff I would only expect to find in tropical waters were right there in Alaskan waters. If I lived there I'd be happy with a tank with native species....although I'd guess I'd have to have a chiller to keep the water cool.
Again, Welcome.
