^^ If you were to hit search and see how many times multiple pairs work out as opposed to having it end badly you will see overwhelmingly negative outcome by far.
The occasional exception is what tends to fool people, especially since it can take a long time for clowns to mature/spawn and show their typical nature.
There may be rare exceptions, yes, but I don't base my advice on those rare cases, but rather the by far most common outcome, and I just don't advocate people experimenting or say "just go for it dude, I only had a few deaths"!LOL
