You can put lionfish with anything the same size or greater. which means no inverts damsels or clowns. I have a tang with my lion and they get along great as does all the others because they are the same size and all swim at different levels of the aquarium.
Please don't fill up the Saltwater forum here with erranous crap passed down by the 'forefathers' of aquarium mythology.
You should pick your Lionfish tankmates wisely, as 'anything the same size or greater' could be asking for problems. I know it would not be a wise choice to put a trigger or a puffer with a Lionfish. Although it has been done before, and you and your daddy have probably done it a million times, dosn't mean it is a wise choice for a beginner with little to no experience.
There are alot of options out there, so don't assume that people who have kept fish here at MFK know everything! Keep the doors open to as many all possibilities. We keep monster fish here, but mostly freshwater. Mr Comptonass here, keeps monster saltwater fish, in a very non-monsterous tank.
Perhaps do a little research on an actual reef keeping forum, before assuming that a person from Kansas, referring to himself as 'comptonass', has all the answers.
His opinion is just 1 of millions, and I find his opinions to be false in most cases. Please read up and practice proper saltwater husbandry, before you make a large investment!
