lets see, they've moved around a lot and its been a long time since i bought them... when i first bought them (i bought the two together) i think i had them in a 10 gallon brackish (or fresh- i forget) tank, i got bored with that i think six months later and had them in my 46 bowfront salt tank for another 8 months or so... then they went back into a brackish 10gallon for a few months, then i started another 30 gallon salt tank, got bored with that, broke it down and made a sump for my salt tank out of it and they lived in there for a few weeks, and i bought a new 30 gallon made it into a freshwater planted, they were in there for a few weeks untill they ate one of my platies, so i dropped them back into the salt water sump where they live with a damsel and a cat shark.
They are hardy little guys and i'd have to say VERY adaptable. They have NEVER gotten sick through all that moving and disruption.
As far as beak problems, i don't know that i have had to do anything, i can see their little teeth, but they don't seem to have any overgrowth problem- i can't say that i've ever heard of that happening in puffers (i'm no expert by any means) but if it is a problem, they must be doing something to wear them down- maybe they shew on the shells and bits of
crushed coral they come across in the tanks?
there was a website called
www.chunkypuff.net that had all sorts of info on puffers- totally dedicated to it, but it was hacked last fall i think and she hasn't gotten back to fixing it yet, its such a shame to have lost all that info and for someone to be so mean on a fish website.
at any rate i hope this helps some
