Buying cheap plants from the Far East is an absolute crap shoot if keeping shrimp. Plenty of accounts on here and elsewhere of shrimp wipeouts after receiving plants treated with pyrethroid and neonicotinoid pesticides, the later of which are especially pernicious and hard to remove.
Having lost all my shrimp twice to the above I'll never buy cheap imports again. You also tend to get better quality with EU grown plants, but where possible I buy from other members on here, or garden centres/pond suppliers for plants like hairgrass and Lileaopsis.
I'm all for saving money where possible, but it often seems to be a false economy when it comes to commercial aquarium plants.
