There are several "Candiru" sp. that are occasionally imported under a variety of names. The main drawback of these species is that they do not travel well. I have tried twice to bring some Candiru back from Peru but they never seem to make it past the importer.
I would be interested in someone managed to get a healthy batch to the states.
I also plan on going back to Peru in 2009 and trying to get Candiru again as well.
