Behavior change
My dominant male has been sitting in the same spot all day, not moving much. He did go to the top of the tank for a minute or two then returned to the same spot.
His top fin is down which is also unusual for him, he’s usually a show off.
Water parameters are all 0 for ammonia, nitrite, and nitrate- tested today when I noticed the odd behavior- ph is stable at 6.9 in this tank.
3 males and 6 females plus fry
He is pretty aggressive with flirting and mating. Should I be concerned or is it more likely that the girls “put him in his place”?
No major temperature fluctuations lately and he ate normally last night. No physical signs of illness that I can see. My 2 oldest females are a little bigger than him but not by much, both of those girls are very close to having another brood of babies.
