The Stone Fish
Most venomous fish known. Up to 12 inches long, perfectly camouflaged, it looks very much like a stone. Only dangerous if stepped on or caught. The dorsal spines can piece through a shoe. The pain is excruciating and can last for months with tremendous swelling and death of tissues. Amputation might be required. If not treated, stone fish stings can often be deadly.

Very poisonous.
Yes, most of the time it is due to stings from anemones, corals or poisonus fish. I would imagine fish can suffer nerve trauma as well that would cause paralysis.
Sea anemone are not poisons to humans in fact they are not poisonus us to some fish such as the clown fish. Sea anemones use their poisons has their defense "weapon". Sea anemones are helpful to clown fish because that's wear they live and clown fish predators are threaten by their poisons.So to answer your question no they are not. :)
