Have had few tanks in the past all salt, not sure why i didnt start with fresh which i hear is easier. Last tank i had a coral banded shrimp take out all my fish and me and the wife felt discouraged and sold that setup. Recently saw my daughter(3 yrs old) was liking seeing fish swim, like when go by koi ponds and on tv. So took her and my son to a fish store to browse and well with finding nemo movie ended up with a tank with clown fish and now they want a larger one to get dory. Started small with a 10g pretty sure will be upgrading in near future and do corals and get so more things. Not gonna lie me and my daughter sit and watch them eat and move around. For me its more of checking health but find it relaxing and peaceful.
