On a side note here.. my expectations were to see hit and miss spawns from my SMB.. what I have observed is not what I had anticipated. What I thought may possibly be unfavorable spawning conditions have shown me I don't know Jack about SMB.
If they are "in" the water, it is highly likely they will pull off a spawn. Recruitment may be a different story but reproduction occurs in conditions the "books" say they won't reproduce in...
