Hi wantsome8

puffers are awesome.
Brackish OwNz!
:)

anyways,

1. sure, use the fluidized sand filter
2. yes, i think your filtration should be adequate.
doesn't hurt to have more tho.
3. i would keep 2 in a 40g
4. 1.005-1.020
5. get a hydrometer and use marine salt - i use Instant Ocean
6. puffers can be aggressive, but i keep mine with a mollie... the one baby that didn't get eaten.
7. sometimes... it all depends on individual personalities of the fish
8. um... up to 4-6" from what i've read.

good luck, and have fun.

Check with the lfs you are getting them from as to what specific gravity they are beeing kept at. Usually FW. You'll have to raise it slowly. Mine live with bumblebee gobies.
