Last night mine went mad for peas! Frozen peas that I had let to defrost partially in the fridge for about half an hour. They must have eaten a pea or two each!! The guppies in particular loved them. The only nuisance about it was cleaning up the remains after!!! I did leave them to feed for longer than usual as it was more difficult for them to eat. They were still at it half an hour alter but by then I thoughtr they had all had their share!! I did peel the skins off them and cut them in half too.
They also love cucumber and courgette!!
Peas were fab last night though! They really loved them!
