shore crabs, shore hermit crabs and shore cone snails will do fine in reef tank.
More so, and better chance of survival if you collect during hot summer days and in tidal pools where temp is high and it will be easier for them to get used to your tank environment.
Don't worry too much about introducing different types of bacteria in your tank because its already a pool of bacteria in billions per ml.
Local crabs will not help you with bubble algae at all, well not in the amount you need anyway.
Survival in closed environment depends largely on the critter's immune system and less so on our tank husbandry.
As for the hitchhikers like worms etc its no different when you buy anything from J&L or any other local pet store.
I hope that this will answer your question little better than the above ideological debate.
