Tropical fish?

I went to the garden centre last week and a lad who works in the fish part put in some of the tropical tanks some chunks of cucumber and he said they like a bit of cucumber. And after three days you take out the leftovers. has anyone else heard that? because I never knew they liked cucumber.

Tropical fish?
Goldfish and cichlids are usually known for eating plant matter, but there are some types of tropical fish that like to eat plant matter. Mollies are a great example. They like to eat dark leafy lettuce, cucumbers, zucchini, and aquarium plants.





HOWEVER, I would suggest taking any uneaten food out after 6-8 hours, not 3 days! Another thing is that you want to avoid making the fish bob for the food floating at the top of the water. Get a suction cup clip that can hold the pieces of food you are putting in the tank. Some fish stores sell them for this purpose, but I'm sure you'll be able to find one at a grocery store.

Reply:Depends on the type of fish, but a lot of them will eat cucumbers and other veggies. I don't cut them in chunks though, I have a little veggie clip with a suction cup that sticks on the inside glass, I'll put slices of cucumbers, zucchini, squash, romaine lettuce, spinach leaves....just about all my fish love their veggies.
Reply:i have gouramis that love veggies. if you cook it down some (technically you blanch it) it helps them eat it better. any leafy greens, chopped up peas, zucchini, cucumber -- all good choices.





fish that eat greens actually benefit from them. mine will color up better and it keeps their digestive tract clean. some fish are subject to blockage which can lead to constipation and internal bacterial infections if they aren't fed lots of greens.
Reply:yes i have heard of that fish love cucumbers. Also try, Romaine Lettuce, squash, flightless fruit flys (at petco andpetsmart)Also at petco are algae pellets. Usually for algae eaters, but all my fish will nibble.
