update:5/16 sick fish please help
sadly one of the dwarf puffer looks like it may die, its inactive and sluggishly floating around the bottom of the tank. It moves away if something is moved by it, and it can swim up, so I do not beleive its swim bladder. Its not discolored, starved, or bloated. No signs of damage/fin rot/irritated gills or body. No visible lesions/parasites.. and I don't see white poop in the tank but I have not seen this specific fish poop recently to confirm its color. The other two are swimming around just fine. They were all drip acclimated for a couple of hours to make sure they would not have shock from the water parameters when they were received on Tuesday of this week (its now friday). Ammonia and nitrite=0, nitrate=20 range, ph constant 7.5, temp 78F. This fish was eating fine and swimming around normally several hours ago with the others. Now its got that half dead floating thing going on... can anyone offer suggestions as to the cause, or a cure that might save it?

3 dwarf puffers arrived yesterday (sold as Carinotetraodon travancoricus). One is noticeably different form the others as it is smaller and the larger spots on its body have a metallic/reflective blue (or even blue-green) hue rather than being black. Has anyone else seen this in their dwarf puffers?
1 of the 2 'normal' dwarf puffers

blue spots

pardon the blur, little buggers don't want to hold still.. exploring their new homes and all
I think they're too young for it to be male vrs female.. and googling it I only found one instance of a person mentioning this in a yahoo answer, but not sure how credible it is..
"Though first described in 1941, the Malabar Dwarf Puffer Carinotetraodon travancoricus did not become available to the United States until the later 1990's, and in 1991 a color variation of this species was described, the Dwarf Imitator Puffer Carinotetraodon imitator.
This fish was probably imported simultaneously with the Malabar Puffer. Whether a distinct species, subspecies, or a variation is not yet determined, but the Dwarf Imitator Puffer is distinguished by having blue spots."
Anyone heard of this?
