Plant Eating Buenos Aires Tetras Help.

Hi all,

I have 4 buenos aires tetras who have eaten to the point of no return my Bolbitus heudelotii that was attached to my drift wood. I have replaced this with java fern in the hope they won't eat it too. They have also taken a fancy to my Pogostemon helferi which is hanging in there but not for long I fear.

Is there a carpet plant that they will normally leave alone that could replace the Pogostemon helferi

Thanks,

Dan
