Blue ringed octopus

[Fishfanatic]

Ok 1st off I know if it bites me there is no anti venom and the only way to survive is to have CPR performed until the venom wears off. And 2nd I do not have kids and would never consider getting one if I did. The main reason I want one is because it stays small as I want to get a smaller custom cube made for it not really picking it because of the rings so if anyone now of another small easy to find for sale octopus please let me know.
