I feel I have done a terrible injustice to my new Sargassum Trigger. He's on the bottom, and barely hanging on. What's the proper feeding them? I have a 180G tank, coral and fish. Water test 5 days ago was good. I'm still pretty new to all this, even though the tank has been going for 1.5 years, I allow a aquarium service handle a lot. I told the place where I purchased the Trigger my setup, as far as other fish, he said he would be fine. I may be tang heavy. Here's the fish...... Foxface, hippo, 2 clowns, damsil, chromis, sailfin, scopus, Australian Harlaqin tusk (I think it is), naso tang, khole tang (which I now haven't seen either of) I lost a new copperband to. I think I saw the scopus being a butt towards my trigger. I don't know.....I love the fish, I feel I'm putting the wrong fish together.
