Well, it didnt turn out as well as I had hoped. they passed the dreaded three day mark effortlessly though. they were healthy and wonderful so i certainly give my appreciation to sustainable aquatics.
The group of nigripes stayed tolerant of each other for several days. They naturally broke off into little pairs during the night. Some slept in a large scolymia. some under the powerheads. and some stuck to the undersides of my magnificas. they would recollect during the day. very shy. they would never enter the tentacles of the magnificas, only hide underneath them. over the course of the two weeks i had them, they never seemed to develop an immunity to the sting of their tentacles interestingly enough.
but one was slightly larger than the rest, and once she figured that out....she was relentless. just a continuous attack on the other four nigripes. it persisted day after day. all five of them were constantly breathing heavily in a way that would signal brook, but they never lost their appetite. it was just exhaustion at being chased and harassed all day long by that one ever so slightly larger clown.
eventually i decided to catch them all and separate them. i had them in a 29 gallon, separated into pairs. just in case, i added a bit of copper to their water and within 12 hours all five were dead. i was shocked.
coincidentally, a friend of mine also purchased five SA nigripes and added them to his existing wild caught pair. (his existing pair had come from a store that had had them for months and were well acclimated and healthy.) his wild caught female also was completely intolerant of the others. and while his tank is larger, also contains several magnificas and all the captive raised ones were eating and doing fine in spite of the incessant female....all five of his died simultaneously a day after mine.
it was like all ten of our fish had a death switch inside them that somehow was activated. bizarre.
so the lessons learned from this:
nigripes do not form groups in aquariums. this may sound absolutely obvious, especially to people who have had nigripes and know how aggressive they can be. but with five fish all starting as captive raised juveniles, one would think there could be a possibility a hierarchy would form especially with large anemones available to them. this was not the case. pictures often show very dense populations of nigripes over one anemone. apparently five captive raised juveniles is not the magic number in attempting to recreate this.
existing nigripe pairs will not accept additional juveniles. there was hopes they would be tolerated in a large aquarium with large anemones available. but this was not the case. completely unaccepted.
so all together it was a very humbling experience for my friend and i. the quality of SAs fish was great, and i will hopefully get some more nigripes from them. but this time....only two.
