I am looking into getting another tang for my 150g display, 72x18x27. Currently I have a 4 1/2 - 5" yellow tang that has been in my system for around 8 months, purchased as a small juvenile. Other fish I have: coral beauty, 2x ocelleris clowns, azure damsel, yellow tail damsel, banded shrimp and that is it. Will definitely be adding 2x lyretail anthias' soon. I wanted to add another tang, leaning towards a juvenile yellow eye kole. Any suggestions adding the kole to my tank with the yellow? I keep reading to use caution with multiple tangs..
