- Care Requirements
- • Minimum 50 gallon tank with excellent filtration and strong water circulation • Temperature range 72–80°F; maintain consistency to reduce stress • Salinity 1.023–1.025 SG; puffers are sensitive to salinity fluctuations • Feed 2–3 times daily with varied small crustaceans (mysis, copepods, amphipods) to support high metabolism • Do not house with small fish or invertebrates—will nip and consume them • Provide live rock for hiding and enrichment; avoid stressful net capture whenever possible, as stressed puffers release toxins harmful to tankmates
- Diet
- carnivore
