Puffer fish are basically not good community fish, and it is always best to keep them in a species tank (on their own, one puffer species). Having said that, there are some exceptions possible...but not here.
Congo Puffer (Tetraodon miurus) is
not a community fish. Seriously fish has this:
It is not really safe to house this
species with anything else! It is a voracious
predator that will eat any fish it can fit in its mouth, and will usually take chunks from larger tankmates. It is also completely intolerant of conspecifics. Some aquarists have had success keeping it with
armoured Loricariids.

Just for anyone interested, with those puffer species that
might manage in a community tank, you have to very carefully consider all the individual requirements/behaviours of the fish to ensure each species is truly compatible. For example, puffers are not fast feeders, so any "aggressive feedeing" fish will not make good tankmates. "Aggressive feeeders" does not necessarily mean physical aggression, it means the species is a ravenous determined eater and fish that are not similarly inclined teend to get frightened, and may even refuse to eat. Loaches are more aggressive feeders than corydoras catfish, which is why these two groups should never be together. Danios (like the Zebra) are aggressive eaters and should never be housed with slow eaters like gourami. And so forth. Another issue is fin nipping, by pufferfish and some other non-puffer species, either way or both.
