The male is probably 5.5 inches if I had to guess, no bigger. With the 2 remaining females tailing behind at about 4.5. not even a year yet, and they have been getting a spurt the past two months and getting thick. I do 80% weekly water changes
I hope. He holds down the middle of the tank while each female hold a side of the tank. Then I have the goofy vieja lol. They don't mess with each other and the vieja just does his own thing.
