Problem next to feminine Cockatiels?

I have 2 female cockatiels that are about 8 years ancient. One is a Latino and the other is a Pearl. I have them in a huge cage and nurture them a pellet diet. They have plenty of toys etc. The problem I am having is my Latino won't leave the other one alone. She's constantly following her around and picking at her feathers and basically her in general. You get these cute little peep, but then the Latino gets too rough and you hear them screech. I try to break it up by squirting them beside a stream of water and that settles them down for a bit. I also give them time out of the cage, but the Latino still picks on the other one even after. Yet, they both seem to love one another and the Latino screems if I take the other one out to the vet etc. What can I do roughly speaking this ? I've looked at all kinds of websites and even here on Answers, but no one seem to have that kind of problem.

umm I contemplate maybe try just seperating them. Please do not take offense to this I am positive you are a great owner, but perhaps try sspending more time with them both, seperated. try selling the big cage and buy two smaller cages. They might in recent times not like each other...

Hope this helps. Answer my request for information (can be about any bird)
in good health first of all if the lutino one isnt causing any mar then you really don't need to do anything. what you described sounds more like usual cockatiel behavior then fighting or whatever. whether the lutino is actually injuring the other or they are in actual fights, you will obligation to seperate them (theyl get used to it). but otherwise just let them stay together.
