Neither will CURE parasitic infections. Cleaner wrasse mostly feed on mucus and larger multicelled parasites. I’m not sure what cleaner gobies go for, but they are prone to developing ich, so then “who cleans the cleaner”?
The benefit is that you get a fish that looks nice and may help out with disease. They just won’t eradicate a disease.
No, they can control certain parasites and keep the fish from developing severe infections, they just can't eliminate the infections entirely, and don't work well against protozoan infections. Some public aquariums use large groups of neon gobies to reduce fluke infestations in their displays. I've always had issues with cleaner wrasse pecking at other fish, especially stingrays and bottom dwelling fish.
Yeah, I realize there's no magic to them just looking for something to support my UV, healthy diet, selcon and cleaner shrimp with disease management. So, do you have a pic between those two? I've seen something that said the wrasses were more dependent on parasites for their diet and wont get enough to eat. I'm looking at captive bred in each instance though and they weren't. I could buy FIVE gobies for what a wrasse costs.
