I'm thinking it could be a patternless but I'm not good with morphs yet.
All I need is repti carpet
My experiment with repti-carpet was short-lived for many of the reasons Seamus cited.
Repti-carpet is terrible stuff.
It's made from synthetic fibers, recycled plastic actually, drawn and formed into extremely fine microfibers, pressed into mats and cut to size.
It frays quickly but not cleanly, loops and partial frays are a common occurrence. These can catch, trap, constrict, damage and remove toes and teeth- or even limbs if it is allowed to go too long before being discarded. Incidental consumption of strands can also lead to impaction or digestive tract damage.
What's worse, the shape and size of the individual strands, stacked in densely the way they are, makes it pretty much impossible to truly dry after it comes into contact with animal waste or when it is washed. Water combined with an enormous microscopic surface area makes it a festering environment for bacterial blooms.
It's really a very poor product. Material fatigue happens quickly and it is impossible to keep reasonably sterile. If you are avoiding particulate substrates, go for the tile or slate options others have mentioned. Do not follow the bad advice of the single person* who suggested the repti-carpet garbage.
*if you have experience with reef forums, you are probably familiar with the phenomena. Sometimes people show up and participate by setting themselves into the role of an educator when they really aren't qualified or competent to be acting as an informational resource. Don't know enough to know how little they know, y'know?
Yep that is a Patternless, or possibly a Patternless Albino, a good eye shot would be needed to say for sure.
