That is the great thing about ponds! There is always room for one more! If not, just dig an expansion! My husband is going to kill me...if I keep pond planning the way I am now, we won't have grass to mow.
I just got a mini Ryukin and about a three inch Shubunkin. I wasn't planning either. They Ryukin was a pitty buy...see my post on my last shopping experinece
hereThe Shub I just got is really cool. He is all blue with big black dots all over him. Yours is really pretty! I'll have to get some pics of mine.
