The Petco silk plants appear to be virtually identical to the Blue Ribbon Vibran-Sea silk plants. I am not sure if they are made at the same factory, but I suspect the answer is yes. I have a Vibran-Sea fern in Odysseus' tank and in Galahad's tank is the fern from Petco...the leaves are exactly the same cut, size, color pattern, etc. They also have a few smaller ones than the kind I could get off Amazon. The only thing that does look different is the base -- the Vibran-Seas have a hot pink base and Petco's have a natural looking base.
By the Petco silk plants, I do not mean the small plants in the betta section that are labelled for betas. Those are ok, too (I think), but they are not as soft, and not very high quality, IMHO. I own a couple of those, too.
