allens damsel great fish if you're adding more than one I suggest upwards of 5, they do kill eachother also best to add them all at once. Being a damsel they do carry the traits and can be agressive to smaller fish, typical behavior fin nipping body shaking and constant harrasing but again only to fishes it can dominate. I have it in my fowler for over a year now with great success but have tried to add 3 more and they all perished. In a reef tank it's iffy cause if you have smaller fish than it then they may feel uncomfortable with it's harrasment although it really depends on your livestock put it with bigger agressive fish and it dare not mess with them, my pseudo and him face off every now and then but nothing serious. One thing nice about this fish is the colours it's gorgeous the blue is satin and deep purple under different lighting and although alittle agressive it shows alot of character wish I could keep more than one.
