The golden would be awesome. I have wanted one for the longest time but cant force myself to cough up the $200. IMO, I would go with the puffer but be prepared they will chomp on anything and everything they feel like and are very messy eaters. I have a dog face and a hawaiin big eyed squirrel in my 75 bowfront and they get along great. I just think the Golden is an awesome fish, ofcourse, puffers are one of, if not my favorite fish so my opinion is a little bias.
