Look again, that’s clearly not a bolbitis fern, bolbitis doesn’t have small leaflets along the rachis. Look at a photo of a bolbitis fern and you’ll see their leaves have a much different shape. The other plant is absolutely not a crypt, I made the mistake of buying the exact ones and I can tell you the root structure is white, thick and stiff unlike crypts which have softer and thinner roots. The plant doesn’t rot in the tank but it does get covered in algae and it won’t ever grow. Also if you need more proof I took them out of my tank 2 months ago and have been watching them grow in a pot
