The Puffer Forum

Fahaka puffers are one of the top killers in the fish world. They will cause enough damage to each other to wind up with 2 dead puffers.

Thanks for telling us about Spot. I had a fahaka puffer Filbert, who lived 19 years.

What filtration are you using? How many lbs live rock? Protein skimmer, powerheads?
When you say, "full" WC, how much is that?

IO is the cheapest salt around because it doesn't include the minerals for corals. You need marine salt, not sea salt.

Nope

Oh gosh... IDK then

I don't suggest using water from the ocean, as it comes with pathogens that fish in captivity may struggle with. You may use the least expensive marine salt, that's usually Instant Ocean.

LOL! Is that why I have 8 tanks? 1 I just can't get rid of is my 10g hex, even though I haven't used it in many years.

How cool! Maybe 4th time is the charm.

If the smaller tank they're in now is cycled, add all the substrate, decor & filter to the 55g, along with Tetra Safestart to the filter. Add more aragonite sand to fill the bottom at around 1".

I don't believe in long acclimations. Once you open the shipping bag, the ammonia shoots up. 8 is enough to cause permanent damage to the gills. Do you think that "bump" might be air? That could cause her to swim wobbly. What do you have in the tiny tank she's in to keep the waste from poi...

Poor puffers! Please DO get that 55g ASAP.

A single F8 is good.

Do you mean F8 (Figure 8 )?
