Hey guys I i started a small 15gal , and was just going to do 2 percula clowns,a gobby, zenya, mushrooms, and polyps. Sorry for any wrong spelling . Am not trying to do anything major as you can see just very simple corals. Tank is cycled with a 50gal rated protein skimmer(overkill I hope?) , 5 gal sump with live rock, in tank live rock 10lbs+, live sand. Just wondering at the same time if I could first add the percs and the polyps? And maybe even the zenya at then same time? Or would the zenya be to much added at once? and then later on the others. Tank is cycled (fishless cycle). Thanks
