BeginnerFishKeeper Posted December 9, 2021 Share Posted December 9, 2021 My betta fish is swimming along the side of the glass 80% of the time. The glass he usually swims along is near the heater and filter but I don’t think that’s related. He will swim along it, swim towards it as if he were “digging” at it, and he’ll turn around and go back and forth along that side of the aquarium glass. Is there a reason for this? Is there something I need to do to limit this behavior? I’ll include some water parameters. Ph 6.8 ammonia : 0 ppm Nitrite : 0 ppm Nitrate : 20 ppm Kh : 0-1 dkh Gh : 12 dgh Link to comment Share on other sites More sharing options...
Bjorn Posted December 9, 2021 Share Posted December 9, 2021 Maybe he sees his reflection? If the inside of the aquarium is brighter than the room outside it sometimes acts as a one way mirror. If that could be the case try turning down the aquarium lights or increasing the brightness in the room and see if his behavior changes. Link to comment Share on other sites More sharing options...
Bjorn Posted December 9, 2021 Share Posted December 9, 2021 (edited) I forgot you could also try placing a non glossy background around the sides of the aquarium. Girl Talks Fish made a video about this. She writes for Aquarium Co-Op. Edited December 9, 2021 by Bjorn Link to comment Share on other sites More sharing options...

That’s what I thought too, but even when the aquarium lights were off he’d still do it so I wasn’t 100% sure. I will try to use a non reflective background and see how that works, thanks!

PineSong Posted December 10, 2021 Share Posted December 10, 2021 How long have you had your fish in this tank, and how long has he been doing this? Link to comment Share on other sites More sharing options...

He’s been in the tank for 2 weeks now and has done it since he first got in there Link to comment Share on other sites More sharing options...

I've had a couple of fish spend more than the average time adjusting to the tank before they stop glass surfing or doing weird things, and they still turned out to be fine. If you don't already have them, you could try adding plants or a betta leaf hammock or things like that to perhaps make him feel more secure/provide enrichment. 1 Link to comment Share on other sites More sharing options...

Yeah I have a decent amount of plants and also have a betta hammock (although it keeps falling off the wall and I don’t know why). I’m trying to get my plants to grow more so my betta has even more cover but that’s a whole other can of worms 😂 Thank you for the help! Link to comment Share on other sites More sharing options...
