Hello wrasse people,
I'm in need of your advice. My tank, a 59” x 27.5” x 19.5” 160 gallon total volume, is wrasse dominated, with plenty of inverts and corals, including zoas, SPS, LPS, gorgonia and Clams. I have been getting away so far with only a mix of different snails, a Hector's Goby and somewhat recently two short-spine urchins as my only herbivores.
Although I certainly don't have an algae problem and I'm not really after a spotless algae free tank, there are some patches of algae that is a bit unsightly as the inverts don't travel around all that much. I have been thinking of adding one herbivorous fish, but I can't decide on what. I want my wrasses to remain the star attractions, so don't want any compatibility issues with the current and any future wrasses and would prefer something smallish, under 5", maybe 6" max. Also also don't want issues with my corals and clams. Lastly I need at least some filamentous algae to keep my Hector's Goby fat and healthy. Any suggestions?
I've narrowed it down to Ctenochaetus tangs, perhaps tominiensis or truncatus, but worry about aggression. I've read from
@eatbreakfast that they may be especially problematic with Macropharyngodon wrasses, so I worry about my lapillus pair.
My other option is a blenny, perhaps Ecsenius or Salarias. I've always liked the Ecsenius personalities and quite like E. pictus. they remain small and I don't expect compatibility issues, but might be a problem with my corals and especially clams. Perhaps not if well fed? Salarias on the other hand get bigger, and from what I read also aggressive, and again might be an issue with corals and clams.
Is there anything else I should consider? What do other people keep in wrasse dominated mixed reefs to control algae?
