So today I purchased a six-line from recommendation of LFS. He is the only fish in my tank. I bought it to hunt down any parasitic isopods if there are any left. I have a 29 gal with 20 gal sump. My ultimate goal for my tank is a mixed reef with pair of clowns, fire fish, midas blenny (or orange-spot), and royal gramma. From my understanding the six-line will terrorize most if not all of these fish. How long would be a good time to keep the six-line to eat any isopods before moving him to my brothers bigger and more aggressive tank? What would be the best order for adding the other fish, I’d think any of the blenny, gramma, and fire fish can go first and clowns last? Any help will be much appreciated!
