What puffer is this? help

I got some puffers from a local online fish store, they claim that they are Amazon puffers, but told me they needed brackish water ( I know amazon puffers are full freshwater). Since the majority of amazon puffers are wild caught I doubt that the seller got them shipped from south america considering they sold them for $3 each converted from local currency, no one else sells this puffer anywhere I look, even at some aquarium fish market I frequent, so I highly believe that these puffers were locally caught and people who sold them thought they were amazon puffers.

I watched all the videos on youtube on amazon puffers and looked everywhere on the internet for a photo that looked like my puffer but to no avail. The stripes on my puffer are too straight to be an amazon puffer, and the body colour and shape are different, although the personality of the puffer are similar to the amazon puffer description.

does anyone have any idea what type of puffer this is?
thank you in advance

 

Almost looks like a colomesus asellus.

yeah, it fooled me the first day I had it, but I noticed that no photos online resembled this puffer, and the more I look at it the more certain that it's not colomesus asellus. I'm confused whether to put him in fresh of brackish water, I have him in a freshwater tank at the moment

 

What did your lfs have him in brackish or fresh?

They had them in brackish, but claim they are amazon puffers which are full fresh water

 

To me, it looks like a relative of the amazon puffer (c.asellus), colomesus psittacus... many s online look pretty similar.

Yeah, I guess it does look quite similar, but the stripe characteristics and body shape still does not match, this is driving me crazy

 

To answer your question put it on brackish water if that is where the store had it you should match it vice over thinking it. IMO.
