When these are gone, I may get more. Not sure yet, as I am still entertaining the idea of converting this tank to a brackish fiddler crab tank when all current inhabitants are gone, but I'm still undecided on that. And I'm really liking the skirt tetras' behavior. They are more lively than the other tetras. Not aggressive, just lively. Their bossiness is confined to their own group. They ignore the other fish. Also, there is a bamboo shrimp in the tank and they leave her alone too. I think that a larger group of them would be very interesting. The next time I stock fish (oh, notice how I said "the next time" and not "if I choose fish rather than crabs". . . hmmm) I am thinking a species-only tank. I'm putting these guys on my consideration list. I should think about something besides tetras too though. Oh, the possibilities!
