I'm not advocating ID or trying to irk evolutionists with this question, but how did symbiotic relationships such as the cleaner wrasse evolve? I can't figure out why other fish wouldn't eat the cleaner wrasse before they had a chance to figure out that it would be beneficial not to eat the cleaner wrasse.

This isn't really an attack on evolution at all. But most fish won't try to eat a cleaner wrasse if its doing its job, and if its well fed. If its hungry, a meal is a meal, and the wrasse is getting more from the deal anyway.
Symbiotic relationships happen when one animal figures out the behavior of another more dominant animal, and figures out how to benefit from it. Sometimes this is to the dominant animals benefit (symbiotic) and sometimes its not (parasitic).

Natural selection would work both ways for a symbiotic relationships like cleaner wrase to evolve. The fish which would eat wrasse fish would be less healthy and reproduce at a lower rate, wrasse fish that would graviate to fish that would not eat them would reproduce at a higher rate. Over a number of genrations, both the wrasse cleaner and the fish it lives with populations would crowd out those with a predator /prey relationship.
In other words, natural selection is not a survival of the fittest, but those with the optimum reproduction fitness..

Well I imagine there would have been a strong evolutionary driver for the cleaner fish to get more food by eating the parasites off living, not just dead or half-dead fish. There are studies showing that cleaner fish use tactile stimulation (stroking and brushing) to pacify the host fish. I guess this behaviour could have evolved from feeding off half-dead, then less and less half-dead fish. On the other side of the coin, those infected fish which passively allowed cleaning would also be more likely to survive. Perhaps thru enjoying the sensations the most and/or having an adversion to aggression towards the cleaner fish species.

Symbiotic relationships are a problem for evolutionists. The termite, for example, cannot digest wood. However, the bug in its stomach digests it and converts it into an edible form. They cannot live without the other, so how did these evolve?
Don't feel you have to shy away from ID and creationism. You can learn much more if you studied science from this viewpoint.

evolution isnt real thats why you dont know.
(sorry i know thats a dumb answer but its true!)
