So I’ve just picked up a pretty much brand new fish (last Friday) and this guy seems a lot more aggressive than any other fish that I’ve had. I’m used to the Bettas flaring a little bit at the tank wall and dark patches on the background wallpaper but this new fish struts and flares as he patrols the whole tank, but especially at the background and me, or the filter even if the lights are off and he shouldn’t even be able to see his reflection on the walls. I’ve only had him a few days. Should I remove the background? Get more plants to break up the reflection? Or is this something some Bettas do for the first week in a new tank and he’ll relax eventually? He still seems a bit nervous in the new tank, today he FINALLY explored all the caves I’ve given him to hide in.
Also, if you have any thoughts on his tail type that’d be great too. He was labeled as ‘bumblebee’ whatever that means. Also, the rip on the tail was already there when I got him. I figured it’d heal up in my clean and cycled tank. I’m not sure what blowout looks like...
