‘Bentley’ the humphead wrasse is helping to dispel the common myth that fish have short-term memory. Keepers at the National Marine Aquarium have trained Bentley to come to the top of his aquarium in response to the noise of banging a gate to a neighbouring pen.

It is believed that over fishing from the aquarium industry has caused the drop in wild numbers of this species to the point where it needs protecting. The reason for my surprise at this news is that I regularly see the documentation of successful captive breeding of this fish and have seen captive raised specimens for sale in my local area and there is really no need for there to be so much pressure on this species in the wild.
