Quote from above link (liveaquariua): "Ideal tank mates include: Livebearers, Tetras, Danios, Barbs, Rasboras, Gouramis, Rainbowfish, Cory cats, and Plecos."
This is totally rubbish; first they wrote that the fish is living in brackish water, then they give some fish for tank mates, that don't live in brackish water at all...
10 gallons would be quite small for it, although it's small fish.
If "dwarf puffer" is
Carinotetraodon travancoricus, then it isn't good tank mate with Bumble bee. It lives in fresh not brackish water. (And water isn't so alkaline either).
Here is some information about "dwarf puffer":

Remember to keep cover closed, this fish can easily jump out of your tank. Don't either make them "to puff", because thay can die of it.
Edit. 1) However, Im not sure, are we talking about same fishes at all. Reason for this is simply; fish can have many different names in english (I have seen, that one fish had almost 10 diff. names!!) or the name means couple diff. fishes. So confusing them together, it's quite common to me. That's why, I hope, you can use scientific name too - then there is no possibility to confusing.
