Red and blue are the most common colors, I don't know about more dominant.
yes you can but you need to give him water changes everyday.can i keep a betta in aa 1 gallon aqua culture fish tank and if so how to make sure it does not die
I've never saw an irid x red offsprings before,do you have a picture to show it?Red is mainly dominant on the fins - irid x red = irid body with red fins. It is also hard to breed out.
