These fish have one small dorsal fin, a small anal fin, a beaklike mouth with fused teeth, and no scales or ribs. They produce tetrodotoxin which is highly toxic to fish and humans. Most are marine but a few are freshwater. Diet: Benthich invertebrates such as sponges, stony corals, tubeworms, mollusks, etc. Final Note: Puffers should be given mollusks with shells to allow them to wear down their teeth. New arrivals may need to be dewormed before putting in the home aquarium. A dead puffer must be removed immediately before its toxin is released into the aquarium to kill other fish.
