Hair Algae

- Chinese algae eater
- Otocinclus catfish
- Amano shrimp
- Nerite snail
- Red cherry shrimp
- Mollies
- Swordtails
- Guppies
It is important to note that not all fish species that are marketed as algae eaters will consume all types of algae. Some species may specialize in eating certain types of algae, while others may consume a wider variety.
