i understand dwarf puffers are brackish but will they live in a tank with no salt?
ive seen these in planted tanks but i dont want to add any salt into my tank incase it starts to kill my aquascape.. and also will they kill my smaller community fish.. cardinals guppys etc

thanks

They aren't brackish, 100% freshwater.
I have kept them in a large shoal in a heavily planted tank and they are just beautiful. But they will nip other fishes fins, so I would recommend keeping them as the only species in the tank.

Here is some good information and more links: Dwarf Puffer

there nice fish. however i allready have a community tank so if i do i might only get a pair.. ive allways wanted something different and my LFS's are all crap and stock nothing but the same old same olds. these were a supprise to see. but i think ill keep my tetra's for a while :)

You cannot keep even two Dwarf Puffers in a community tank. They will eat the fins off of all your other fish.

I keep Dwarf Puffers in my planted tank along with amano shrimp and oto's which are really the only recommended tankmates for them.

I would like to invite you to vist my dwarf puffer site at: http://www.dwarfpuffers.com

I like that fauna combo :P
