Quick Answers

Will plecos clean my whole aquarium?
No. Plecos graze surfaces, but they do not replace water changes, balanced lighting, or proper feeding.
Do plecos need driftwood?
Many plecos benefit from driftwood, caves, and hiding spaces. Check each product page for species-specific needs.
Can plecos live with shrimp?
Many smaller peaceful plecos can coexist with adult shrimp, but compatibility depends on species, tank size, and setup.
How big do plecos get?
Adult size varies widely. Always check the product page before buying because some plecos need much larger aquariums than others.
Are plecos covered by the Live Arrival Guarantee?
Yes. Photograph any loss in the original sealed bag on the day of delivery and submit a claim through the Start a Claim page.

About This Collection

Plecos

Plecos are freshwater catfish known for surface grazing, unique patterns, and bottom-level activity. Smaller plecos can be great additions to mature community aquariums when tank size, diet, wood, and hiding places are planned correctly. Plecos should not be purchased as a complete algae solution. Most need supplemental foods, stable water, and appropriate space as they grow. Check each product page for adult size and diet before adding one to your aquarium. Fish require Overnight shipping and are covered by our Live Arrival Guarantee. Review product details for tank size, compatibility, and care notes.
