I am starting to like a lot fairy wrasses, in fact I want buy 2 instead of a blue tang I wanted to buy, since they are smaller.
I don't know how difficult it would be to keep them. I have an acrylic tank, as you know, they don't have closed lid, but it has a central acrylic border, also on top there is a current Usa lamp that does cover the complete opening, but is not sitting on the same level, there are about 3 inches between the lamp and the top openings. I don't know if jumping would be a problem. My fish do get scared sometimes, the tank is on the kitchen.
Also I have heard they are planktivores but that can accept other kinds of food, I feed my fish pellets, and shrimp twice a week. Haven't used zooplankton yet, planning to in the future since at the moment have only corals that do not require it. And also I don't wanna do a mess with water, feeding plankton all the time.
Appart from that, the tank is incredibly stable, it doesn't even have a heater, and the temp is always the same, an anemone died once, and nothing happened to the parameters, its only a 65 gal.
I do have a banded coral shrimp though, don't know if the wrasses could kill it.
The royal gramam I own, is very territorial
