RABY Bay residents were surprised when a bait net, cast off a pontoon in Warner Canal, dragged up a stonefish.
Len Branch, who lives on the canal, caught the stonefish the same week two were found at the beach at Amity Point, North Stradbroke Island.
Redland City Council is considering an upgrade of the Amity Point swimming enclosure after the fish were found.
Stonefish spikes carry a highly toxic poison.
If stung by a stonefish, call triple zero and immerse the affected limb in hot water.
