Nana toxic?

[sqwerc]

I just read the most worrying thing.. Nana is toxic!!! Haha I just wanted to check with the more experienced brothers here with regards to this. I have quite a quantity of them in my shrimp and fish tank. Read that when cut they release a toxic sap that can kill the tank community.

Is this true? I can't say much from personal experience as none of my fish have died and I'm new to shrimp and have been having weekly shrimp deaths. Keep them because they are a hardy easy to maintain plant.

Not true, I used to have big clump of nana, in my previous tank and I trimmed frequently and my shrimp love sleeping inside those bush. Sometime they even went to scratch the newly-cut stem (out of curiosity?). In fact, soil is more toxic than cut nana so to speak. So go ahead to cut, cut and cut if you find it gets a little untidy!!!

nanas' sap can be deadly to high sensitive shrimps. Thus you will NEVER see shrimp breeders keeping them. correct me if i'm wrong.

This is the mixed information I've been getting from looking around on the web. Some say it's toxic some says it's not. I have a bush in my shrimp tank and many in my fish tank. Just want to know the facts and if my shrimp/fish are not in any danger.
