Thank you, already have 2 wrasse and heard damsels are aggressive? Love to have a trigger but might be a conflict with my shrimp?Personally I think you're missing some fairy wrasses. Go with slightly more aggressive species like the cebu pylei fairy (Cirrhilabrus briangreenei) and the pink headed fairy (Cirrhilabrus chaliasi). A larger group of smaller damsels like azure (Chrysiptera hemicyanea), green spot (Neopomacentrus azysron), gold belly (Pomacentrus auriventris) or even green chromis (Chromis viridis) would also look very nice, while adding relatively little bioload.
Niger triggers are also an excellent choice. This is my new guy coming on Saturday morning from NY Aquatic.
