The Puffer Forum

No, it looks like he just had a meal.

Could be a cyst. May pop on its own.
They need crunchier foods. 90% of their diet are snails.

What test kits are you using? You should be showing some nitrate.
If they were just breeding, it could be bites from their mate.

Thanks for the update! My 1st fahaka lived to 19 & was great with most tankmates. My 2nd one killed anything in his tank.

Great shot!

I don't think ANY puffer would "thrive" in a community tank. They need special foods & are slow to get to it.

They don't appreciate being moved and sulk for quite some time on a hunger strike. Try live food, as this is what they are used to eating in the wild. Even when I moved mine from a 55-gallon to 125 (which I thought he would appreciate), he wouldn't eat for 2 weeks.

That's all good.

Sure--just gut-load them 1st.

I would QT the snails for 3 weeks. They can get busy during that time!

Thank God, Walmart doesn't sell fish anymore!
Good to see you here & thanks for the update.

Not fat, just full of food. Has it gone down?

Feed him whatever he'll eat in 5 minutes.
