Perhaps you have a fish that hogs all of the food; in which case, why not buy two? Once one ring is filled with food the greedy fish will dash straight to it, leaving the other ring free for your remaining fish to feed in peace from. Using multiple rings allow your fish to choose where, and with whom, to feed.
Manufactured from durable polyethylene for maximum durability, this fish feeding ring features 3 separate compartments ensuring that the food is contained and not scattered all over your tank.
Dimensions: 23.5cm diameter x 1.5cm deep
