Can too much seaweed cause health issues

I have recently moved my green spotted puffer over to the reef, he's been doing REALLY good in there. But he has become obsessed with the seaweed that i have in there for the angel. He is eating at it all day long and is pretty protective over the clip as he hoovers over it pretty much all day, he'll leave for a little bit but he'll come right back. I ahve had to put a second clip in the tank just to make sure the angel gets seaweed.

I have noticed he is always bloated and belly is partially black, meaning a sign of stress.

I am just concerned about his health because he is not used to eating veggies and now he's been eating it all day for the past two days.

What harm can too much seaweed do, or should he be ok

 

i would think he would be fine. but im not 100% on that.

 

DO NOT SMELL THE BUBBLES

:d

 

^^^^ lol

 

i would take the seaweed out but i have to leave it in there for the angel, he's still eating his meaty foods on top of the seaweed.

I just got home from work and he has a MASSIVE belly and is very bloated and still has the black stress markings, i dont know why he wont stop, he doesnt stop eating it, i have noticed he has been constipated and having a hard time pooping

 

I eat tons of seaweed (with my sushi) and I'm doing OK...
