I used to have two beautiful true perculas. One was much larger than the other. They would always hang out and swim together. One day i came home and the much larger clown had jumped out. Of course by the time I realized this it was too late. Would it be ok if I purchased another percula clown for my now lonley smaller clown fish? If so should I look for one much larger than my other clown or smaller? Thanks for any info.
