Yes, you have to trim a pea puffer’s teeth. All pufferfish, including pea puffers, have four teeth – two at the top and two at the bottom. These teeth are triangular in shape and interlock with each other. If not trimmed, these teeth might overgrow to the point where the puffers cannot eat anymore, essentially starving them.
Trim a pea puffer’s teeth once every 4–6 months to prevent overgrowth. Additionally, provide your pea puffer with hard, meaty, and crunchy foods to keep its teeth trimmed nicely.
Snails are fantastic foods for keeping your pea puffer’s teeth trimmed. However, make sure to only feed them small snails, approximately the size of their eye, so they can bite the shell properly.
