I tried but it was too big-one it hits the bottom they show no interestHave you tried not breaking it in half? I've seen 1" dats taking Hikari floating Carnivore whole. They're just holding it in their mouth but definitely not letting go. Looks really cute. They'll eventually take it in when its soft enough and you'd think that one is enough to fill their tummys...then you see them go for another. LOL.
