American flag fish or Amano shrimp?

[MichaelL710]

Hello aquarium co op forum. I have an 40 gallon aquarium tank that's been running for 4 years. In the beginning of tank I had black beard algae and I still have some remnants left to this day. I was thinking about putting in some flag fish or ammona shrimp I have 5 otos and 7 juli Cory's, 11 beckford pencilfish, 1 Bolivian ram. Which one would be better at eating the alage and that won't over crowd my tank. Thank you ufor any responses.

Flagfish is my vote for what your looking for as long as your filtration is adequate

The flag fish are quit a specktical.as for filtration on the 40 gallon aquarium I have an canister filter fluval 207. Would that be enough?

I also have alot of vallanseria.

That is a stunning Val display.

Thank you it took a while for them to grow but once did they did. They never stop growing

If the BBA has been there for a long time the amanos will likely ignore it unless you do a spot treatment to weaken it (loosen it) from the surface.  Based on that, you might have better success with the flagfish in this case.

I would probably do both. I like to have some amano shrimp in any tank I think they won't get eaten. I think you could also afford to add at least one flagfish.
