I wouldn’t rush on the acro’s your chances for success with them in that new tank are very low.. reefing is a long term hobby and nothing good comes from rushing, I personally wouldn’t put anything at all in a new tank for the first 8-12 weeks even if it’s cycled and then I just do a few cheap LPS or softy “tester” samples over the next few months to see how they do.. IMO acro’s should only be introduced into a stable and well established tank that’s a year or more old unless your a seasoned Reefer and know what your doing and same goes for that clam... rushing can cause unnecessary failures and larg amounts of lost money which ultimately leads many people to leave the hobby.
