I find that none of my fish interact with their plants or decor at all! Which is kind of annoying, considering how much i've paid...
Seth is the only one who sleeps in his fern plant and hides/swims around his jug-type decor. And Aryen had a purple Colour-burst plant he used to swim in and out of all day. The rest of my bettas completely ignore their stuff and swim at the top mainly. Does anyone else have bettas like this?
Edit: And JUST as I finished typing that, Roald Dahl goes into his statue for the first time and comes out of the bottom. Silly fish.
