Lack of nutrients/light has prevented the parva from growing and spreading.

What type of substrate do you have?

No matter what its holding on and nice and green.
Separate slowly/easily into 4 chunks and plug them together.
Provide root tabs about 1 inch away from the rhizomes and you should start to see more growth.

This is a bunch I put together, not one piece. They have been throwing out new leaves, but still at a very slow rate. I have high tech, high CO2/light, EI dosing, and aquasoil, so that shouldn't be a problem.

that picture looks like normal submerged parva to me.
interestingly, when i grow mine emersed, the leaves get a LOT bigger. but then when putting it back in a sbmerged environment, the new leaves come out small again. very variable growth depending on the environment.

i have had my parva for over a year now and it has not spread much. but then 1 pot does not go far with this plant lol. it is a really slow grower and leaves can very on the same plant. that is how mine looked when i got it. the leaves are a bit wider now but if the shrimp pull bits up and they float at the top of the tank for a week or so they start looking like that again. in general crypts tend to better in medium light. i might be wrong but i thing they can burn if to much light is used? feel free to correct me if im wrong im no expert on plants
