Cress in an aquarium?

[Tooombsy]

Hi guys. Been a long time since I was on here.

This may be a silly question. My gf has been growing cress on the kitchen window sill, just the stuff that grows on a bit of wet cotton wool.

I couldn't help noticing it would make quite a nice carpet in the tank, does anybody know if:
A) it would be harmful to the fish
B) if it would even grow fully submerged in water

Thanks in advance for any replies

It shouldnt harm your fish.As for submerging it I would try one submerged and one floating just to see how that goes.Also no fish will really try to eat it cause it has a peppery taste
