One of my clients has a juvenile porcupine puffer, ( 3-4) in. The fish developed "Lockjaw". Diet has alway been frozen krill. I took the fish and force feed with a pureed mixture of octopus, squid, shrimp, and pea's and a supplement of Vita-Chem, in food and in tank water. We force feed with a syringe and flexable air line hose. After 5 feedings the condition reversed and he's able to open his mouth and eat on his own. The problem is that all he will eat is krill, and I know that if the diet is not varied, the problem will reoccur. I'm all most afraid to starve him for 3 or 4 days, now that he's eating again. Any suggestions are welcome.
