I have yet to find a plant that Buenos Aires tetras and Silver Dollars won't eat.

Searches mention Java fern, but they seem to find that tasty.  I've tried about 10 different types of plants.  I'll keep trying. 🙂

Try crinum. My friend has severum lawnmowers for fish. The crinum lasted quite awhile before that got mowed down. Anubias did ok for awhile also. They have the best luck just using lucky bamboo and other emergents.

It's funny.  Some new plant types won't be touched for days.  I start thinking "Eureka! I've found it," only to have it mostly disappear the next day (once they "discover" how tasty it is).

You might try planting fast growing swords like Amazon swords like Echinodorus bleherii in pots to let them get well rooted and established, growing well, then move into the tank.  They can mostly outgrow the fish in my 75 G Jack Dempsey tank and they’ve lasted better than anything besides the emergents.  This tank has an adult pair of Jack Dempseys who seem to do the most damage trying to rearrange the plants (mine are held down with very large pebbles/small stones).  I’ve also got 7 juvie to subadult tiger silver dollars, and 2 festivums that are near adult to adult, and only recently 2 very mature bristlenose pleco males waiting for me to somehow catch the female out of my 100 G nanofish tank so they can hopefully share a girlfriend unless I luck into another adult short fin blue-eyed lemon female or at least subadult/large juvie.

They’ve been very hard on one pot of the swords recently but there are still 2 pots of them in there doing well even if they look a bit beat up now and then.  If I fertilized more the swords would probably look better.  😆

I'm hoping to find something that they find distasteful.  The search continues... 🙂

Anubius coffeefolia held up in my cichlid tank where Java fern and other anubius did not. Dwarf sag grows so fast for me that I would consider it since they won’t dig it up probably

I’ve never kept the tetras, but I can tell you silver dollars will eat any plant in the aquarium. They will decimate all of it, it’s just what they do.
