[Quetzalcoatl]

I think I have heard of this before too, but in my last layout I had HC with Rummynose tetra and saw no problem. SAE was causing more problem then anything else for me.

Is HM Hemianthus micranthemoides aka baby tears? They definitely didn't have any problem with any of my fishes (Rummynose, Cardinals, SAE, Otocinclus)
