There are soo many types of Crypts that it would be hard to put them all into one post.
I’d love to have someone chime in and talk about individual species of them. I haven’t really seen any that were particularly harder to keep then others. I have a some crypt Spiralis for sale over on Aquatic Jungles as it is a hardier Crypt for beginners.
I will say that they might melt right when put in there. They will come back after they melt, and they’ll come back even better. I’ve never really been able to keep them without dirt. With dirt, they will start to send runners and do well.
They are also a good low light plant.
I have to give my Crypt loving AGA buddy some love…
Check out his setup and let him know I sent you..
