Hi all! I have a quick question about my Crowntail betta Remus. Currently, I've got him and two albino corys temporarily in a 10g until summer when the corys will be hopefully be rehomed to a bigger fish tank. Remus gets along with the corys really well -- he doesn't show any aggression towards them at all and I've made sure to monitor him consistently to make sure. What he does do, however, is hang out by my filter and flare his gills at the glass. I'm pretty sure fish can't see their reflection (?), so I have no idea why he flares his gills at the glass. There's nothing on the other side of the fish tank except a mini-fridge with bottles on top of it. No other pets, no other animals, no pictures, etc. He shows no aggression to anything else EXCEPT that! Does anybody have an idea why?
Also, I added a bubble wall and I can't tell if he's pissed that it's there.
Do bettas generally like bubble walls, or do they roll their eyes and scoff?
Thanks!
