Help new Tetraodon schoutedeni

Hello all. Brand new to this forum, I’ve been in the hobby for 3 years but I am new to puffers. To start off, her are my parameters and Info on tank.

Water parameters: pH 6.6-6.8, Ammonia 0, Nitrite 0, Nitrate 5

The tank is a 20Gal long, tank mates are 3 Sterbi corydora and 1 two-inch spotted Raphael cat.

The tank is established, and been running for over a year. This is a new fish so I don’t have a feeding schedule to give since I’ve had it for one day. So far I have fed it twice ( freeze dried krill, since it seemed to ignore the snail, however I did drop two snails in there but did not witness if it ate them or if they’re somewhere in the tank I cannot see. Not that the puffer in question is affected by the water change schedule since he’s new, but I do weekly 25% water changes. I have only added Prime and recently a dose of Flourish since it it’s a planted tank with Java fern and anubias. Before typing this I did do my normal 25% water change.

So the concern is, I’ve got this new Tetraodon schoutedeni. It arrived yesterday afternoon. I noticed he has a lump on his belly, towards the back. Upon close inspection, it appears almost translucent. Appetite does not seem to be affected. I also noticed he is not moving his pectoral fin. It appears collapsed.

Is any of this normal? Or cause for concern?

Please link me to a photo. Is it swimming normally? What is the pH of your tap water?

pH in tap reads at 7.4. I’m not sure it’s swimming normally. I’ve noticed it swims vertically quite a bit but not sure I know what normal is for a puffer. I will try and upload pictures. I tried earlier via my phone and the files read too large.

More pictures showing what I suspect is fin rot. the edges of the collapsed dorsal fin are white.

I'm wondering what is causing your pH to be so low. It concerns me that it isn't closer to your tap water. Start doing 50% weekly WC or more.

Wish I knew the cause of the pH difference too. Isn't my pH of 6.6-6.8 within the range for the T. schoutednei according to the link you provided though? In any case, I ordered some Kordon methylene blue from Amazon, but it wont arrive until Monday. Thanks for you time and responses.

It is but should resemble closer to your tap. I always suggest 50% weekly WC or larger.
