Tht stripes shown when they are stressed actually..male also had it..happen when introduce to new environment or bullied by other male or female..not exactly show breeding mode..thanks for advice- I already introduced a small school of females to the male, and they swim together in the betta community. two of the three have spawning horizontal stripes.Originally Posted by supergourami<br />
=what I did was I got a 5 gallon tank , lowered the water level too around 6-8 inches , make sure you have a place for the bubble nest to be made ( half a Styrofoam cup and some floating plants is perfect.) lots of hiding places for the female. also when introducing the female don't just toss her in use a oil lamp or some sort of divider to let the 2 fish get used to eachother. once the flaring dies down release the female into the tank.
