The best foods for plecos include:
- Algae wafers or tablets
- Sinking pellets
- Brine shrimps
- Frozen or freeze-dried bloodworms
- Cut-up vegetables, such as zucchini, lettuce, and kale
You should also keep driftwood in the tank. Aside from being a nice hiding spot, driftwood is an excellent source of food for plecos.
Make sure to feed your plecos one to three times a week. Because they’re nocturnal, you should feed them at night to maximize their food intake. Also, only provide them what they can eat within five minutes to minimize waste and prevent water contamination.
