Barnacles vs. Seahorses

I googled barnacles
And for real! WHO THE FUCK WOULD CHOOSE THAT OVER SEAHORSE!?
Not try mention they trigger my hole-disgust

"Barnacles. Because I hate my siblings"

Barnacles, because if it is ugly enough, you can kill everyone.

Not to be that guy, but seahorses are so incredibly hard to take care of and keep alive That the right answer is probably barnacles. Especially if this younger sibling is a child. Dooont get your child a seahorse please.
