What other fish can be put with figure 8 puffers?

Figure 8 puffers can be housed with other peaceful, non-aggressive fish that thrive in similar brackish water conditions. Suitable tank mates include mollies, some species of gobies, and certain tetras, as long as they are not small enough to be seen as prey. It's important to avoid overly aggressive or territorial species, as well as any fish with long fins that might provoke the puffers. Always ensure there is plenty of hiding space and consider the size of the tank to accommodate all inhabitants comfortably.
