IMO mixing these particular fish can be done on a short term basis. I don't think 4-5 years down the line it's going to work. So if your ok with taking the chance of you lion getting killed then go for it. Me personally I would rather suggest more compatible fish for you and set you up for long term success instead of saying yea it perfectly fine and have your fish suffer later on down the road.Jmo
