Vegetable treats?


Small Fish

Hi all, I was wondering if there are any small vegetables I would be able to cut and and give to my fish as a treat?
At the moment I have three male guppies, one neon tetra (his buddies passed away) two julii catfish and two kuhli loaches.

On a side note, the guppies seem to harass eachother on and off. Not a real problem as they don't seem to tail nip, but they do get stressed. Any suggestions on how to ease the tension? Thanks.
