My local PAH has the Dutch iirc snail/shrimp friendly plants in again...

First time since early January. Don’t know it they’ll be everywhere but if you’re looking....

I bought a couple of plants last week from an Ebay seller who sells shrimp safe plants and they arrived with a "UK plant passport" stamp on the label, so they are now arriving from Europe. I know of three European plant growers - Tropica, Dennerle and Aquafleur. There may be more.
