Watch Emma Wilkinson's full report
A couple from Oxfordshire who were poisoned by a lethal toxin in their own home, say people who keep coral in fish tanks need to be better informed of the risks.
Emma Mundy and Chris Matthews from Steventon became ill when they breathed in palytoxin - which it's believed was released from some coral into the air as they were transferring the contents of their tank to a new tank.
They ended up in hospital, along with four members of their family and the first four firefighters at the scene.
Peter Mundy, a manager at The Goldfish Bowl aquatics store, says palytoxin - which can be life-threatening - is found in some coral species, such as zoanthids, and is used as a defence mechanism against fish and other corals.
