A common misconception exists among aquarium aficionados, and it reinforces the idea that beginners should stray away from larger fish and stick to the little guys instead.
This couldn’t be further from the truth. The bristlenose ancistrus, for example, is an excellent species for novice hobbyists in the field, as it is medium-sized and skilled at tank cleaning.
The Bristlenose Pleco (as fish lovers know it best) is one of the most common aquarium Plecos and a master of disguise, featuring colors and shades of brown, black, grey, or olive.
They feature bony plates on their bodies and they sprout branches (think about them as some sort of tentacles) from their heads when they reach maturity.
They are spectacular in sight and even if they look fierce with their horns and armor, they do not fare well in the presence of predatory and aggressive fish.
They will, nevertheless, defend themselves against semi-aggressive and small harassing fish, but try to keep a peaceful environment.
