Don't all fish have spiney dorsal fins?
Quite frankly NO they do not... take sharks for instance they do not have spiney dorsal fins.
While I did not find anything either on Hawkfish being venomous, I didn't exactly mean they would shoot out toxins, and nowhere did I say that they were hollow like the Lions. I guess by secrete it sounded that way, however, not what I meant to say. All fish have a slime coating which when poked by the spines, it leaves this behind causing irritation.
I know that you have been fishing before and caught a fish that happened to poke your hand and in return you had a painful little sore.. If you haven't well, hmmm can't help you there... I was mainly relating to the LFS
guy who told Triggers that they were venomous.. technically he could have had one poke his hand while having it in the tank and he was allergic, which caused him pain, I do not know this, however, it sounds good... This of course is speculation, however with no supporting fact from the LFS
guy who knows...
