The Orange Spot Bristlenose Catfish, similar to the peppermint bristlenose, boasts a dark body adorned with small, vibrant orange spots. As a tank cleaner, it can be found in almost any aquarium and excels at consuming leftover food and maintaining algae levels. Its water needs vary from soft to hard and can tolerate a range of Gh levels from 2 to 20. While it can live in acidic, neutral, or alkaline pH, extreme conditions should be avoided.
