Frequently asked questions
Why did my Mint Charlie melt after I added it?
It is sensitive to transition, and stems grown emersed often shed their original leaves when first submerged or when water parameters shift. Keep conditions stable, leave the stems planted, and watch for new growth from the tips and nodes — that signals it has adapted.
Does Mint Charlie really smell like mint?
Yes — crush a leaf and you get a distinct minty aroma, which is why it is grown as a culinary and ornamental herb above water. In the aquarium the scent is irrelevant; people grow it for the cheerful light-green, small-leaved texture.
