Questions on Cleaner Wrasse

The Fourline wrasse is a cousin of the Sixline with an even more aggressive personality from what I have read.

 

Yes there is also a Four line Wrasse Pseudocheilinus tetrataenia.But I believe the O.P.was looking at cleaners.
Cleaner Four Line Red Sea Wrasse

 

Are six lined considered aggressive?

 

They become aggressive to newcomers after becoming established to a tank. IME it was only with fish that spend time in the rocks.

 

The problem I have with these discussions is that "leave it in the ocean" is not a viable option. Once a fish has been captured, it's not going back. It will die in the LFSes tank or at the hands of a newbie unless someone who understands their needs (or is willing to research) gives an honest effort. Furthermore, you can preach it on every online forum available, but you'll never reach enough people to stop the capture and sale of the Cleaner Wrasse or anything else. Perhaps finding a way to supply their needs and spreading the word would be a better answer?

Once upon a time, all we had for SW fish food was frozen brine. It was a widespread belief that brine was the staple for all SW fish. Naturally, only a handful of fish survived captivity more than a few months, mostly damsels and clownfish. We learned better, and we've done better since then until only a handful of fish remained in the "leave it in the ocean" category because of their feeding habits or dietary needs. Now, even the Mandarin has been made an easy keeper, although one still does best with a tank-raised specimen and some special care.

I expect to get slaughtered by the naysayers, but I recommend trying Ocean Nutrition Prime Reef flakes. There's something in it that attracts mine to eat and provides his needs. He has doubled in size since I first rescued him in January, and he's fat, healthy, very active, and just as aggressive at feeding time as the Damsels. I was concerned at first that I may have made a mistake, but today, I couldn't be happier.
