Allright, which one of you ate my cucumber?

Question

I left 2 thick slices of cucumber in my tank last night to collect snails. I managed to collect 2. When I picked the cucumbers up, there were huge holes all over the cucumber. I have a molly, guppies, neon tetra, and swordtail. Oh, and 2 new otos. Could they be the culprit? I'm just very curious, because I might give my fishes cucumber once every week or so, and is it bad?

Answer 1

All of the fish in your tank are vegetable eaters. Some other veggies to try are Zucchini,lettuce and spinach. Any veggies should be "blanched",that is,dropped into boiling water for about a minute,then rinsed in cold water to stop the cooking.
Your fish will "graze" on the plant material all day.
Your pets will love it.

Answer 2

Basically every fish you have, but the neons will happily eat most veggies. The otos are plant eaters by nature, and live bearers need a fair bit of vegetable matter in their diet. I'd try zucchini, or broccoli stems as they have more vitamins than cucumbers. Note that it may take a day or so for some foods to soften enough to eat.
