Hey y'all thanks for the advice about my tank.. I took y'all advice and went ahead and gotten rid of a lot of the fish and changed the LFS I was going too.. I had and now I just own 4. Engineer goby, small marine betta, hawkfish, and greenbird.. Was wondering what will be a good addition to these 4? I was looking into a puffer or trigger.. Any advice y'all can lay out for me?
