My crypt undulata has had 3 weeks to melt and be dramatic, but I can’t really tell if it’s doing anything under the fuzz. How long before I can say that I gave it a good run before I yoink it for something else?
My anubias, planted at the same time, gave me a new leaf so I’m not totally hopeless.
Crypts are infamous for their initial melting and slow growing. If I were you I would leave it another couple of weeks at least. It might be smart to gently clear away any decomposing debris.
