Cucumber toxicity

[urville]

I was reading on cucumbers. That the most poisinous variety it takes 1g of their toxin to nuke a 25g tank.

So my question is: What are the least toxic cucumbers? Which are at least somewhat safe? Is there a list of which ones are and how bad?

One gentlemen here in town has a black and pink one, anyone familiar with this cuke?

Holothuria edulis is the name... maybe...
Trying to find out for certain.

What about Pentacta anceps.

One time on a site i cannot find now, i read there are some non toxic cukes, is this true?

i heard they were toxic as well but i have never had a problem with my sand sifters. i guess it also depends if you have anything in your tank that is going to attack it.

I don't think any are completely non-toxic. We usually get one that is supposed to be easy to keep and not supposed to release, but I never got the name of it. It's just solid brown, actually it looks a lot like a melted snickers bar if that helps lol.
