nope my tank is only 240, they grew up together. unfortunatly the saddleback just passed away the other day. I dk what happened he was just upside down with all this red stuff on him. was my favorite fish. just have the 16" miniatus, looking for a tomato grouper or a blueline grouper next. But the groupers got along great, sometimes the saddleback would shake his head at the miniatus when he was near his cave. but they got along with the other fish, volitan lionfish, dragon eel, and some angels.
i'll try and get pics one of these days.
