I currently have a 150g tank with a snowflake eel, male bird wrasse, naso tang, niger triggerfish, and and areolate/red hind grouper. I have looked online and mostly everything said that these could be kept with corals, so I was wondering if I could start a reef tank. I would only do this if my water params are perfect (I know hard to get with these large waste producers) but if I could do that, could I start a reef? Also, what other fish would you reccomend for me to get? Could I keep a volitan lionfish and a harlequin tusk?
