10 year old, 1+foot long salt porcupine puffer - senior foods? Nutrition needs

Hello everybody,
My name is Debbie, and my puffer's name is Jerry. Jerry is 10 years old and still very healthy. It takes a lot of water changes to care for him, but it seems to be keeping him happy.
His diet consists of 1 Xlarge frozen shrimp per day or 1 to 2 fresh steamer clams. I soak the clams in refrigerated tank water for 2days before feeding (only live clams from New England). I've tried lettuce, flakes and cubes but he won't eat them. I soak his food in vitamins and he eats a little seaweed, but I think that as a senior his needs have changed.
Does anyone have an older puffer like Jerry?

Since no one has said anything I'll throw my 2 cents in. I have no saltwater creatures so I've no idea if the same rules apply but isn't it the case that more protein is needed as we age because our bodies have a harder time repairing themselves? Except in cases of kidney problems extra protein is ok.

I would say that if he's acting well, eating and pooping fine, then his diet is adequate. And wow, 10 years! Well done

 

I also have many older fish but no puffers even though I do like them very much.

I just wanted to say well done! Keep it going!

 

Thank you for the kudos. He has been a great teacher.
He does get plenty of protein from the shrimp and clams. I guess that's ok for him in his old age too.
Btw...I've been told by many fish folks that feeding steamer clams is bad for him because of foreign bacteria. I feed him clams regularly because he loves them-literally jumps for joy-and the shells keep his teeth trimmed. I always soak them before feeding.

 

Meh. There's bacteria in everything. As long as you're taking steps to ensure that they're not coming directly from dirty water and they've had a chance to purge any excess nastiness then you've done your best to make them safe
