In slowly adding stock to my new tank I've alot to learn and consider. I have seen 2 types of fish that appeal but need to know pro's and con's. My tank with sump is 200 litres so I won't be having many fish so I'll have to be picky. The 2 fish are firstly a little black puffer (box looking) with white little dots all over. The 2nd being a dwarf angel blue and yellow. I've been told that they are reef safe but will attack any shrimps i have. I don't have shrimps yet so can still deliberate and decided which way to go. Any ideas from you out there. I also love the look of triggers but think they are a no go.
