I’m evolving a mixed reef tank that currently has rock, sand, snails, conch, corals, coco worm, rock anemone, pom pom gracilarus macroalgae, phyto, pods, and brine shrimp. A large wild caught mandarin is on his way to me from Alyssa’s Seahorse Savvy next week slong with 2 small brittle stars and more snails. The website claims the fish are prophylacticly dewormed, but I have no details/confirmation of this. I also have established 2.5 g coral QT with macro algae, gravel, and copepods available. The questions are: 1) should I treat the mandarin in any way, 2) should I observe him in the coral QT, 3) start a larger fresh QT, or 4) place him directly in the established DT. He will get some roommates in a few months. I’m concerned about him eating enough and having his space figured out before room mates come. But I am also concerned he could be a carrier of a disease he is immune to or not showing and then QTing the other fish would be futile when I add them.
