Does anyone know why my pygmy chain swords are pushing their roots out of the substrate?

I have Crypts that do this...well roots grow straight up into the water column rather than down down into it. Since that tank has sand there isn't much/any nutrients in it, so the roots adapt to where the nutrients are. I dose EI so the roots can take nutrients from the column much better. Likely what is happening in your case also.

ok, that makes sense. thanks for the info

How long have they've been planted? Did you add root tabs?
