I recently posted a thread because I noticed the colour of my Betta fluctuating. It was suggested that he may be stressed due to a new tank habitat and the fact that he is now in a divided tank and can see my other male.
However I have also read about stripes and I was wondering what the reasons for vertical stripes on a male Betta are. Mine has had his colour fade and vertical stripes appear on and off.
Is it just from stress?
Do they get these vertical stripes when they are ready to breed? (I have read females do)
I have blocked off his view from the other male and added more plants. each has a cave to retreat to which i have faced away from each other for extra privacy. I have also put a light above their tank which has helped regulate the temperature because I am battling to find a small enough heater. He seems much happier but that was yesterday so I need to monitor him still and see if this continues.
Also, he is big and mature but has never attempted to blow a nest bubble which concerns me. He is fat and healthy and very active even when his colour fluctuates and these strips appear. His appetite is good too. Im wondering about these stripes that have appeared lately though.
