I have a 125 gallon aquarium that I'm planing adding a few corals to, mainly just some mushrooms, pineapple trees, or other hardy corals. Not a lot I want the main focus to be fish. I might also had some sea stars, tuxedo urchin, and maybe a lettuce sea slug. If those are not compatible I will be fine without. My main question is why are puffers not reef safe? I'm not going to add any crabs(unless I add it to wear down the teeth), shrimp or small fish if that's the problem. I'm mainly looking at getting a dogface or spiny box. Let me know If any of you guys have tried this before or how you got around it.
