BOLTON Aquarium now has 12 new tiny piranha fish, taking over from Gnasher, who was the oldest in the world. Sadly, he died last April. These small fry are growing fast and always hungry. A must-see for fish and aquarium enthusiasts. If you are thinking of buying fish and an aquarium, call Tim Henshaw or Pete Liptrot 332200 for all the advice you will ever need.
