Feeding the fish

A visit to the garden centre with my daughter for a spot of lunch and a browse. This very large tank of goldfish also had a resident sturgeon species which, whilst essentially a bottom feeder, was circling the side of the tank, presumably grazing on the algae.
Every so often it would raise itself out of the water in an attempt to get at the food the goldfish were eating.. This behaviour spooked my daughter. hence the hand raised well above the water as she fed the rest of the fish in the tank.
