What should I do about my pufferfish's teeth at the front of the mouth which are becoming overgrown?
Act now to ensure that your fish can continue to eat properly. You may need to contact a specialist fish veterinarian, who will anaesthetise the pufferfish and trim back the teeth to a correct length.

Start with your regular vet however, as he or she may be prepared to carry out this task for you. In the future, try to include hard-shelled items such as snails in your pufferfish's diet as this should help to wear its teeth down naturally, reflecting its typical diet more closely.
