okay guys, Marbles now has a pot-cave thats seems pretty popular on this site, a plant that looks similar to Bam's, and that gorgeous black lagoon gravel. He is still really wary of the new pot and plant...wont go any closer than about an inch away from them. Seems to be okay though, stress stripes were faint for a few minutes and are now gone.
I couldnt find a betta log there...and I looked for marimos but not only did they not appear to have any, but i dont think i'd have bought one there anyways. Their plants all look so awful. this petco not only takes awful care of their bettas like the others but also take terrible care of their other fish, turtles, and aquatic plants.
Anyways, he seems okay, just not a very bold little boy...he did flare at the pot once briefly...I hope he warms up to it! pics in a while =)
