Bristlenose Pleco
Algae eater that STAYS small (unlike common pleco)
Overview
The Bristlenose Pleco (Ancistrus spp.) is a Freshwater (Tropical) fish growing to about 4–5 in and living 5–12 yrs. It's peaceful and best kept on its own. Plan a tank of at least 30 gal. With a typical lifespan of around 9 years, it's a medium-length commitment.
Is the Bristlenose Pleco right for you?
A good match if — you're new to fishkeeping and want a hardy species; you want a calm community tank.
Think twice if — you wanted several of the same kind together.
What a Bristlenose Pleco needs from you
The ongoing work is water quality: filtration, regular water changes and stable parameters. As a tropical fish it needs a stable, heated tank. Keep it singly, or it will fight its own kind. Don't undersize the tank (minimum about 30 gal).
