GIANT fish have gone on display at Blue Planet Aquarium to warn owners exactly how big some species can get.

A display highlighting the problem of looking after ‘giant’ fish species has been unveiled at the Cheshire Oaks attraction.

The exhibit includes species such as black pacu, red tailed catfish, vundu, tiger shovel nose catfish and ripsaw catfish – all of which have been donated by members of the public after outgrowing their original tanks.

Blue Planet is involved with the nationwide Big Fish Campaign which aims to raise public awareness about making the right decision when choosing pet fish. On average the aquarium receives more than 80 calls a year from people looking to re-house their fish.

Blue Planet’s exhibits manager, Andrea Redfern, said: “As well as showcasing some truly awesome fish we’re hoping this exhibit will also be a useful tool to help the public visualise the size a ‘cute’ baby pacu will grow to.

“Alongside piranha and plec, pacus are among the most common fish to end up homeless when they outgrow their tank.”
