The sixline will limit what you can add. It will complete for pods and be aggressive to the Mandarin. It will be aggressive to a basslet and possibly the Midas depending on the size of the Midas.Need your opinion on adding or making a small list of fish to add. I am looking to throw something in quarantine shortly so here's what I'm working with. I have a 90gallon tank with coral. My fish consists of a Sailfin Tang, 2 Bangaii Cardinals, 1 clown, 1 Hawaiian Tang, six line wrasse, and a cleaner shrimp. I also have some CUC. I do like wrasses but I might have made a mistake by adding a six line first. I also believe I'm maxed out on Tangs.
Blue spotted jawfish?
Convict Goby?
Midas blenny?
Any angels?
Anthias?
Black cap basslet?
Mandarin?
Anything I should avoid or you should suggest?
Thanks
The Genicanthus genus is the only genus of angels that are reef safe, but I wouldn't add one to a tank with established tang. Any other angels are a risk to corals.
Blue spotted jawfish need cooler temps than standard reef tanks. Consider a tiger, dusky, or pearly jaw instead.
