Can anyone recommend any good hardy plants for a fresh water aquarium. I have brought one from a very reputable LFS of which may I add cost £4.75 a plant. It's been in my tank 3 day and it's all dropped to bit and the leaves have fallen off. All the other plants I have are around 1- 2 months old. The fish have not eaten them they just swim around it and I don't know the name of it. Tried to find it on internet but gave up after 5 hours. Any advice would be grateful .
