Could be that the plant was never introduced to fish
You know the plants are cultivated in a sort of damp environment rather in a tank, so it's not that hard to just avoid putting it with any fish/potential disease carriers
But it might be, if you're concerned, a good idea to keep the plant in an empty tank for a week or two.

(I doubt this one's going to last long though, the leaves look very, very tasty and edible )

Oh! How nice! Let me know how long it takes them to eat it

I'm hungry .

Fantailer, you're hilarious!

Ron, I have checked the internet, and all I found was the patent.  It's hard to search on too because there is no name on the package.  Nothing came up in the forums, but maybe if I try searching individual ones.  I used Yahoo!, wonder if Google would bring up different sites.  Thanks

Thanks.

Ha!
I really wanted some more plants in my tank lately... all kinds f plants! But I'm a bit concerned that I'll just have to add some silk plants or something... seriously, SOMEONE is eating the Java Fern and Anubias even! I don't know if it's the Pleco or the goldfish... xD

They sure did like these plants!  They have steadily been decreasing and now only 1 small branch left.  This is their only food source during the week.  I felt bad one day because one of my fish had a really long poo, but it only happened that 1 time.

I also had to throw out a lot of branches that they must have pulled off, that were stuck to my filters.

I have bought some new plants with bigger leaves and will put them in today, I think Java Fern and Anubias.  One was in the "disease free snail free" package, and one in a "snail free" package.  I wonder if they will eat them too, like some of your fish do...

I gave the wrong plant names - I have 2 Green Horemanii Sword and 1 Anubias.  My fish took to them right away, not eating but swimming thru them.  Not afraid of them but very natural and I can tell they like them.  I like having pretty live plants; I have gotten rid of most of my other decorations and will be buying more plants for them to hide in.  My goldfish seem to prefer it that way.
