Hi i need advice on my amanos, i added new plants to my tank yesterday as soon as i did this my shrimp started acting strange swimming erratically and trying to escape. I immediately did a large change but when i got up this morning three look like they're dying the others are kind off hunched up, i have done another change. Is some plants poisonous to shrimp? Ammonia 0 nitrite 0 nitrate 5 before changes. Any help would be appreciated as i have a shipment of cherries coming on Tuesday so I'm panicking!
