I am going to start a tank with 4 or 5 amazon puffers. I was wondering what fish would be good tank mates for them. I know that the puffers are fin nibblers, so the tank mates would need to be fast and have short fins. I was thinking about danios, probably the glow fish or pearl varieties. I also heard that swordtails would work, because they move so fast. Would either of these two species work? Does anyone have any other suggestions? Thanks.
