hey! im not interested in the plant as i already have two but i feel that i must say a few things!:
this guy is awesome! his plants are awesome and quality and superb in every way =)
also, my favorite part of the hobby is the challange i think. i take on crypts which is the second part of the question. i like crypts because they grow slow, they are uncommon and not easy to keep and maintain. anyways, cheers and good luck everyone!
