was between the goonch and para.. chose Paraiba.. large cat thats shark-like in build. While the goonch's teeth are admirable. The Paraiba just seems abit more "realistic" as to what it's requirements in captivity would be and the over-all activity ect... I'm not big on fish that just "sit there". Which it would seem the Goonch would likely be. Like a RBP. Looks cool but unless kept in schools ect. Not gonna be fun to actually own unless being fed.. just my thought process on the matter. Could be completely off-base but... can't go wrong w/ either I don't think.
