Admitted! They DO know more about puffer care/growth. You won't find that I have ever done anything more than ASK WHY does the mbu require a 1000g tank? If you bothered to read some of the previous threads on the subject, there was a wide variance of opinion - even on the puffer forum. I went through and linked the varying opinions that went from 400g to 1000g. And if 1000g is the minimum, how come they do great in an 800? That's a 20% smaller than the minimum tank? All I have asked is for people to provide factual evidence or studies and NOT conjecture.
Asking for evidence or something other than "because I said so" isn't a crime, and nor should it be shunned. The fact that you took offense to my comment and are attempting to bait me into argument only reinforces my point above.
As far as your fahaka, congrats. That's great appreciable growth, but doesn't prove the case one way or the other, even if you did EXPERIENCE it. I guess you're assuming that because I ask a question, I don't have experience with puffers or with fish in general?
