Can Beta fish be overwhelmed by scenery?
With anything new to it’s environment, a betta fish will be cautious of anything new to it’s tank (this is because of their territorial traits). But depending on the betta, it will take a day or so for it to get used to the props/scenery. But don’t be surprised if the betta stays clear of a certain area, he/she may not know if it is safe or not.
