Which blennies are these?

[Zionas]

Hi, I found Chinese e-sellers selling the following kinds of Blennies but I’m not sure what species they are and their care requirements. Would love to know. Thanks. If any one of you is knowledgeable about blennies I’d love to hear from you.

Molly Miller Blennies. They are much like the Lawnmower blennies and eat algae:

Scartella cristata "Molly Miller Blenny", Captive Bred - Shop MiniWaters.FISH - Online Aquarium & Vivarium Boutique

The captive-bred Molly Miller Blenny, Scartella cristata, has it all. Hardy to a fault, they are an ideal captive-bred "cleanup-crew" all rolled up in an under-appreciated but beautiful package. Molly Miller Blennies have been documented to eat detritus, pest algae, and yes, even Aiptasia...

Thanks. Are all of these Molly Miller Blennies? Are they any easier to keep than the Lawnmower Blennies?

Also found these. Not sure what they are.
