In Reply to: Heterostichus rostratus : Giant Kelpfish guarding it's nest of eggs posted by Chris on February 23, 2006 at 10:20:54:

I have been able to get up close and personal to film giant kelpfish mating, laying eggs in the nest and then the male guarding them on several occasions.

You are absolutely right... the males stick to the nest to defend it and will allow close approaches. I watched one over the coast of about two weeks and the male would actually come over to me, rest in my outstretched hand and rub its body against my glove.
