My nebulous wrasse.
Anybody have one in a mixed reef tank?
I have one in my 6 foot fish only. It's the second smallest in the tank, at about 2" or a little over. Just a hair bigger than my H.prosopeion. It is bigger than the one in your video though and a fully mature female as they're a small species.
They are really really tough wrasses. They can be kind of aggressive towards other wrasse, especially other Halichoeres (Mine isn't a fan of my larger male H.richmondi and female Pseudodax moluccanus) but the aggression is manageable. They don't really chase or do any kind of damage to other wrasses, it's more so just a 'lunge' as i've described on this thread before to get the other wrasse away from the general vicinity of wherever the nebulosus is foraging.
But what i mean by tough is basically they are immune to bullying. Kind of like dragon wrasses, in a way. For lack of a better term they have that dog in them. When i first added mine, 2 of my fish had a problem with it. The first was my 3" Bandit dottyback (Pseudochromis perspicillatus) which chased him vigorously for about 10 minutes. they did like 6 laps of the entire tank at full speed, with the little dottyback hot on the wrasses' tail. It was really funny to watch honestly, the dottyback was like a little missile of a fish wiggling it's tail. After about 10 minutes it lost interest and never showed any aggression towards the wrasse again.
Another was my 4" Lightning wrasse (Thalassoma quinquevittatum) which is an absolute beast. It managed to beat a 2" larger Thalassoma lutescens into hiding by repeteadly dive bombing the other fish so fast that it couldn't react. That being said, the first encounter i saw the lightning came up behind the nebulosus with it's fins flared, the nebulosus turned around and did the same and the lightning immediately backed off and didn't bother it again.
In fact, i've had it for about a month and a half now and i recently watched the dottyback swim up behind the nebulosus which was picking some pellets off the sand bed. As the dottyback attempted to feed on the same pellets the nebulosus turned around, opened it's mouth and swam towards the dottyback which turned around and swam away, so the wrasse is actually higher on the heirarchy than the dottyback now.
Tldr can be aggressive (but not harmful) towards similar wrasses, will not be bullied or take any kind of aggression even from larger fish. Females stay small like under 4" so might be safe with larger shrimp and the like. Males get like 5 or 6 inches i think but are never really seen in aquariums.
They're kind of like dragon wrasses but a little less grumpy and mean.
