Yes, plecos can and will eat zucchini. They actually like it quite a bit in my experience. No special preparation is required before feeding.
However, you do have to figure out a way to make it sink to the bottom of the tank. Plecos really don’t like going to the surface to eat food.
How to Feed Plecos Zucchini
As mentioned earlier, no special preparation is required before feeding other than washing the dirt and pesticides off of it. You just have to figure out a way to make it sink to the bottom of the tank.
Some owners stab a clean fork through the zucchini before dropping it in the tank. Others will attach a weighted clip to it and then plop it in the tank.
It does not really matter how you weight it down as long as what you use is safe for the aquarium.
Again, just make sure to wash the zucchini before dropping it in the tank. The vegetables you buy from the store often have soap, pesticides, and other nasty stuff you don’t want in your fish tank.
That wraps it up for feeding plecos zucchini. It’s 100% possible to feed your plecos zucchini, just make sure you figure out a way to sink the vegetable to the bottom of the tank.
If you decide to feed plecos zucchini, then you will find that they will enjoy it quite a bit. I have read stories about some owners feeding their school of plecos an entire zucchini once per day.
