London, March 20 : Lavatory flush tanks can now hold fish too, thanks to a new type of fish tank.
Maker AquaOne has named its extraordinary mini tank `The Fish n Flush'.
The company claims that it is perfectly safe for both fresh and saltwater fish.
The firm even says that the tank can be emptied water, and used for small animals like turtles or lizards.
David Parrish, from AquaOne, said that the tank had been designed with fun in mind, and that reactions to the aquarium had been positive on the whole.
He, however, admitted facing some opposition from people concerned about using the loo in front of their pets.
