I have a pair of Picasso type that's been with me for 3-4 years now. It used to be in a 150g, then a 35g. Now it's in a 300g. They are the first fish introduced in the new tank. I just happened to see an amazing pair at the LFS and I was wondering would it be ok to have 2 pairs in a 300g 8ft tank? When I do get an anemone, would that be a problem? Would I have to get 2 anemones and put them at opposite corners of the tank? What are your thoughts and experiences? Thanks in advance!
