Quite a helpful thread can be found here:
Small brackish puffers
Most agreed on facts (notice the *most agreed on* bit, many people have different opinions on this):
- Min tank required is a 10G
- Min amount of water per figure 8 when keeping more than 1 is 15G a puffer
- SG level of around 1.005
- Limited amount of tank mates though are often reported to get along with bumble bee gobies & knight gobies
Though these puffers aren't the most aggressive they can and will be territorial. You are not guaranteed to have more than 1 puffer live peacefully together, and any tank mates are at risk at any time. Puffers are known for getting along with tankmates for days/months/years and then suddenly turning on them. They are however lovely fish with a whole lot of personality, and even if it turns out you can only keep 1 in a tank, they tend to still be worth it.
