The Puffer Forum

I'm so sorry to hear that!

Hi, I'm moving this to the Hospital forum, so you can answer the Qs in red.

Hi, sorry it took me so long to respond, my internet wouldn't let me in.
Congrats on your new mbu!

Yes, their belly can stretch quite a bit! Are they looking skinny before feeding?

If he looks uncomfortable, then yes. How large is he?

GSPs are not piscivores, so fish (also beefheart) are not suggested foods for them. I suggest spot-feeding the lil guy, while the others are feasting. https://www.thepufferforum.com/forum/library/puffers-in-focus/an-introduction-to-green-spotted-puffers/ https://www.thepufferforum.com/forum/library/...

The only sure way to sex these guys are the tiny wrinkles behind the male's eyes.

If it is not affecting his ability to swim (being an air pocket), then the only thing left is a Nematode worm. There is nothing you can do about this. Just keep his water clean & hope he can live as long as possible with it.

Yes, I have sand & plants in all my tanks. I use play sand from the hardware store but you have to rinse it a LOT! If it is just for a 10g, just buy 10lbs from the pet store. 15g is recommended for pea puffers, so you can keep 5-6 of them. They like to be in groups.

ALWAYS uncooked, with shell on. Cut up the food to only feed enough for them to eat in 5 minutes.
