I am considering getting rid of my PKGs. I was wondering what everyone thought. I want to replace them with something that has bight colors. I don't want anything that lives on the bottom of the tank though. That area is covered. My PKGs are only about 3-3.5 inches right now. They have decided to fight all the time. I'm afraid they are going to hurt each other. I have recently moved them from a small tank to a large tank. This caused them to grow almost a full inch in just a couple of weeks. If anyone has any ideas on what to replace them with, I would be happy to hear them. My other fish are listed in my signature. I need them to be compatible. I also don't want anything that will get bigger than 2-3 inches if possible. They would also need to be able to survive in a brackish tank. Thanks.
