i'm not trying to be mean here but i think you're thread should read, "what isn't wrong?" you told us some time ago that the tangs you had were in bad shape(the pics confirm that) i think you should have concentrated your energy on bringing those back to health instad of getting more tangs.
just because the tangs aren't fighting now doesn't mean they won't later on.
moorish idols are not easy to keep. i think you should have left them where they were.
