"I really appreciate you guys and all the compliments and interest in the pond, but I really owe it to all to you guys. Every bit of success I may enjoy will come directly from the knowledge I've gained from this site."
Jamie, well spoken, accurate and is true for a lot of us. The only bad things in/around my pond are results of my ignorance or not listening. I do think you are being a bit modest tho. Seems like ya may have contributed a good deal of labor and good planning and deserve a pat on the back.
As for the HSB, they are very fun to catch, do not reproduce and can be put and taken as desired. If you add more SMB, with all of the bedding areas you have they MAY want to over reproduce. With the size of your pond I don't see where a dozen or so HSB for an added thrill would be so bad.
Also thanks for providing so much info in this cool thread.

Do nature a favor, spay/neuter your pets and any weird friends or relatives.
