Any Butterflies for 55 Gallon

[CoralBudgie]

Hello:) I was wondering if there are any butterflies that would be happy in a 55 gallon aquarium. The main two I have been looking at are the Longnose Atlantic butterfly and the Klein's butterfly. I can't seem to find much information on the Longnose and I have never seen one at an lfs so I probably wont get one, but how about the Klein's? I have done research on the Klein's and most sources seem to say a minimum of 50-60 gallons for a single Klein's. I asked workers at a couple lfs that I believe to be trustworthy, and they said that a 55 gallon was fine for one Klein's. The main thing holding me up is that Liveaquaria states that 120 gallons is the minimum. The odd thing is I remember going on Liveaquaria a while ago and seeing that 120 gallons was the minimum if you wanted to keep multiple Klein's or have them with other butterflies, but one would be fine in a tank around my size. Other websites have said the same thing, that a single can go in a 55+ and a 120+ is needed for multiples. Would a Klein's butterfly be okay in a 55 gallon? If not, are there any other butterflies fine for smaller aquariums? I have read that pearlscale and Tahitian butterflies are also fine in smaller tanks, but from my understanding, the Klien's is the hardiest. Other fish I have in my tank are a green chromis, six-line wrasse, and indigo dottyback. I also have around 85lbs of live rock. Thanks:)

Klein's, pearlscale, raccoon, falcula,auriga, longnose, and a few others would all be fine singly in a 55g.

Thank you so much. I was not really sure at first, but now I feel better.
