Hi Steve,
120g mixed reef, current fish are:
Radiant wrasse
McCoskers Wrasse
Sunburst Anthias
tailspot blenny
randall goby
I'd like to add (in this order?):
Copperband butterfly
watanabei Angel
Kole yellow eye or lemon mimic tang
1) Any issues with the CBB and either of the tangs or the Angel? no. however CBB are sensitive to the mood of co-inhabitants and ideally should be introduced first. CBB are a mixed bag in terms of success, with the Australian versions being easier and in general more successful. Note the CBB are not guaranteed to be reef safe; about 50% of the time they are not, and they are definitely not clam safe
2) Any behavioral differences between the 2 tangs that should factor into my choice, based on stocking list? kole tang, if available is somewhat more docile
3) Assuming the above is all added over a period of time, would i be able to add a Leopard wrasse of some sort as a final fish down the road, or will the tang and angel prohibit a shy fish like a leopard wrasse? a leopard wrasse depends on species to a large degree. If they are healthy, they are not difficult with peaceful inhabitants, but they should be dewormed with Prazipro always, and need a fine sand for escape when introduced.
Thanks as always for your advice!
