I’ve seen mixed reviews so not sure whether to try this or not, I was thinking to start with 5-7?and see how it goes although ile probably do a bit more research before giving it a goNever tried one but would certainly like to at some point
Some people have not had the greatest of success with doing this but I believe it's due to not keeping them in a big enough enclosure? This of course will depend on how many slings you are wishing to keep together?
It's experimental either way but I wish you luck
