Hi all, so I got myself a large 300L tank with live rock, I then put inside from my little 60L nano my nem and 3 clowns along with my cleaner shrimp, I then added 2 blue tangs and a beautiful little fire fin tang, all are living very well and happy although I feel I may need a bigger one due to the tangs my girl got a cute little pink and yellow fish as she called it when I got home, it’s a small royal dottyback but I have no idea if it will be okay with my other fish and what other fish I can now have in my tank, oh and she already put it in, yes I had a stern talking to her but what’s done is done, now what? Any advice and other suggestions on fish I could get in the future.
