Black Ruby Barb Eat Hair Algae?

Hey!
So i came home after been away from home in some weeks with new fish, cherry and black ruby barbs.

But my tank was filled with hair algae :/ i think its hair algae. Small green hair on the plants like 0.5 cm and on the glass..

Now 2 days later there is less of it. Now i can see the ruby barbs nipping on some plants, do do they eat it or eating my plant? If they do i probebly made the best deal ever

 

Thier omnivores

so yes they would eat some but also feed them some meaty stuff too like shrimp,bloodworms

 

Thats nice to hear! Ye ofc i feed all my fish a variaty of flakes, pellets, wafers and frozen artemia

 

That’s good
