Definitely possible if you do it right. I would just suggest getting them small and growing them out. Be careful with the endli as from what I've seen baby endlis are very cannabalistic. From there just make sure you don't add any really small UJ with the endli. I wouldn't be as concerned with the ornate about eating tankmates, but just keep in the back of your head that if its big enough to fit in there mouth it could end up in their mouth.
