Being the devils advocate.. To publish names without proof is not good.. 🙂 It could have been the plants, no doubt about that, but then it could have been anything else. Although it points to the plants, as it seems the only constant on the two tanks.
Also, you need to share some of that blame; with such an expensive collection of shrimp, and living in London, with ample access to a shops that sell Tropica, and also knowing that Asian plants more often than not have pesticides sprayed on their plants, why would you buy or not have enough care with any plant that you would use on a shrimp tank?

Luis, you make some reasonable arguments here. You are right, I can't be sure it was the plants. For example, there might have been something on my hands (there wasn't by the way, they were clean) and because I put my hands in both tanks when putting the plants in that could account for why both tanks took casualties.
However, let's be clear about what adequate proof would constitute. I would either have had to conduct a controlled experiment with two near identical tanks. Or I would needed to have tested the plants for toxic substances. Obviously I, and almost every other hobbyist, do not have the facilities to do that.
I do think I was foolish putting the plants in with foam and weights and, in the case of the P. helferi, rockwool. I was in a hurry and didn't have time to plant. However, I disagree with you about where I bought from. I think Ed is right in that the supplier has to take responsibility for informing customers about the potential risks of their products. Whilst price was a consideration like Greenjar availability of certain plants was the main reason I bought from them. It wasn't even rare plants, just couldn't get any E. vivipara, which I needed to bulk up the wall of it I already have, from any of the main retailers or either of my usual LFS.
If the supplier is aware of the risks because they know the growers use the pesticide then they are culpable. They have a responsibility to inform customers of that risk. Naturally they will never do that because they will never sell any plants that way but the responsible solution is to not buy in from those suppliers.
To be clear I did not know that this supplier might do this or that far east growers had a reputation for using pesticides/insecticides on plants. I would never have bought from them if I had. I would also point out that I am not a noob. I've only been into planted tanks for a year but have got quite into it during that period. Therefore I would surmise that there are plenty of people on this forum, and plenty who have not even found this forum, who would know less than me and buy from the supplier innocently not being aware of the risks.
As such I feel it is only responsible of me to inform people of who the supplier is. I will not do that on this thread. I don't think that is appropriate and after speaking to a mod I also feel that this might pose a threat to the forum. However, said mod is happy for me to tell people by PM. So if you would like me to tell you drop me a line. Apologies to those who already have and who I haven't responded to. I will do so now.
