Recently I introduced 3 CPO into my 4 foot tank covered with japanese hairgrass. It took them close to 2 weeks to uproot everything.

Now I'm trying to find some plants for my tank that won't be uproot by CPO.

My choices are Nana, spiky moss, german seaweed. As my tank is a low tech tank I can only choice plants with low demand.

Can anyone please advise me?

Thanks
