What's plants go best with dwarf hair grass?

More hairgrass.

Scaping wise or in a biological sort of sense? Anything you want really at the end of the day. Just be careful with other carpeting plants as DHG species can get pretty crazy with the runners.

Is there such thing as plant compatibility? Was it Tom Barr that mentioned that plants will produce an enzyme to stunt other plants' growth in the absence of low nutrients/light/CO2? (kind of off topic I guess).

But yeah, put in what you like best.

I guess some plants can overshadow others really easily if not trimmed due to vastly different growth rates.
That little tidbit about the enzyme is interesting but I would think all plants would be affected so picking compatible species wouldn't really be in the question.

Yeah, I can't remember if/where I read that. I just remember thinking it was interesting too. Not sure if it's actually a thing lol.

I think crypts would go with the dwarf hair grass.

Depends on the setup. In an iwagumi or small tank DHG is many times a background plant. In a more traditional setup it's usually foreground.

Diana Walstad has an entire chapter on "allelopathy" in her book, Ecology of the Planted Aquarium. Allelopathy is the chemical warfare waged by plants trying to inhibit the growth of algae and other plants in competition for resources. I am not aware of this being more/less of a problem with low nutrients/light/CO2.


I don't have the book with me at the moment, but I believe I recall dwarf hairgrass having potent allelopathy.
