Plant ID and can I stop it from being eaten?

Hi everyone. I'm fairly new to the forum and would really appreciate your input.

I've attached a photo of one of my tanks. What are the tall, largest plants on the left side of my tank called?

Also, my shrimp, nerites, and even my otos seem to like eating the stems of these plants near the substrate, so they keep getting decapitated! I then keep replanting what's left of them and the cycle continues...

Any opinions on whether there is anything I can do about this (outside of relocating the animal offenders)? Thank you so much for your help.

Looks like a hygrophila of some sort. My guess is that the stems are rotting off on their own and the critters are not the cause of it.

i have no idea what that plant is. the pic is too small and not the best quality. try and get a close up of the plant, and save it in a bigger resolution.

ottos will not eat live plants. they have a suckermouth, so its to much trouble for them to do that. they will eat dead and rotting plants, so the plant is probably rotting from the bottom up and they just eat the rot. the same goes for most shrimp.
if i had to guess, id say it doesnt have enough light, since from what i can make out, your tank is low tech right?

Additional Photo

I have taken a closer-up photo of the plant and attached it which might hopefully aid in identification.

Thanks for your response Cheaman. If the plant stems are indeed rotting first and then they are being eaten, what would commonly cause this to occur?

I've had this happen to stem plants before. I believe it is a combination of lack of light and not enough substrate fertilizer. Ever since I've increased my lighting and added fert tablets under the affected plants, it no longer happens.

Thanks @[email protected] and cheaman. That is very interesting info on the ottos/shrimp. Yes, the tank is low tech so it would make sense that light is part of the problem. Its a 14 gal, and I currently have 2 coralife compact flourescent 10W 50/50 bulbs in it.

The plant looks a bit like Hygrophila corymbosa 'angustifolia', which does prefer higher light.

Thanks everyone for the information! I have been researching based on your input, and I think that you are correct that the plant is Hygrophila corymbosa angustifolia. I am going to try to up the tank lighting and fertilizer as I would really like to keep it alive. Appreciate the help!
