The new tanks up and running. And i am on the spend again . Any new purchase has to be reef safe and compatible with the current occupants!! ( 5 green chromis, yellow watchman goby, 2 clowns, coral beauty, firefish ). The size of a new fish matters . And the swimming space a fish may require due to tank size ( 83gls-350ltr ). Cost is NOT a issue because it's nearly CHRISTMAS . I did like the looks of a Dwarf Fairy Wrasse , But any knowledgable suggestions will be greatly appreciated. I'd like the next fish to be B) but still obtainable. Cheers
