I intend to upgrade my system to a 75 gallon tank, just to have enough room for a longnose butterfly. From reading the section on these fish in the CMA, I gather they are not hardy, but not delicate either. But after reading these posts, now I am rethinking my strategy. Am I just interpreting the CMA using wishful thinking?
More importantly. would your comments above apply for all butterflies? I am also considering the saddleback, Pakistani/red-back, and the pearl-scale butterflies. Are these hardier?
