A pet store near me has been getting in some pretty wild species lately. They currently have in a couple stonefish, which they're housing in freshwater.?. The only information I can find on them is that they are ocean dwelling and are THE MOST POISONOUS fish in the world.?!? I sort of want one because it would blend right in with my substrate, but I don't know if my other fish would be alright with one in there. I'm thinking it's probably the "false" stonefish or devil scorpionfish. Has any one raised these or possibly know more than I & the pet store do about these.
