Snipe,
Sorry, missed your post.
I have not decided on size yet. I guess it would depend on what is available at the time, and the cost.
Goals are to have a good LMB and HSB fishing pond. Don't want catfish or anything else.
Would it be a concern to add the HSB a year after the LMB? Wouldn't they just be food for the LMB, ofcourse depending on the size of the HSB?
