my puffer dying!

I was just wondering the same thing. You absolutely need a hydrometer. You can get one from the same place we recomended you order the autofeeder from, www.bigalsonline.com. I use a SeaTest, by Aquarium Systems. 1 tsp/5gal isn't nearly enough salt for these fish. What kind of salt are you using? You need to raise the specific gravity in that tank to at least 1.008 & higher as they get larger. To acheive that, it takes around a cup/5gal, but you need a hydrometer to be sure. You will also have to raise the SG over a matter of several weeks/months. Just because the puffers were chasing the feeder, doesn't mean they ate it. I'm sure you now realise the consiquences of the diseases they carry. I hope you are also learning how much your lfs knows about puffers...NOT!
 
Thanks for the advice, my fishs are as active as before i leave now and the white spots are disappearing fast. 2 more days left on the Maracide treatment, and as you guys recommanded i cutted the dosage in half

to answer some questions:
Im using " instant ocean" salt.. i was at first told to use Aquarium salt.. then i was told that it doesnt do anything.. then i was told to use normal table salt... never did that.. then i was told any yet another LFS to use the instant ocean and thats what im using right now. I'll defintly go pick up a hydrometer when i get home in a few weeks.

they are different LFS if u wondering.

What should i do w/ the feeder? should i just flush it down the toilet alive?
 
I think the best way to euthanize a fish is take the fish & tankwater & put into a baggie into the freezer. The fish goes to sleep & then freezes.
 
Take the feeders back and get some frozen or freeze-dried food that is made to feed your puffer.
Throwing them into the toilet and flushing them is adding to the problem.
Fish that aren't naturally found here cause problems dead or alive. Live they compete for food and live or dead have bacteria and foreign diseases that can spread to native fish wiping out hole population or species of fish
Example:
The Europeans bringing carp over to North America as a source of food in the colonial days. Carp eat trout eggs and disturb other fishes breeding beds.

GET INFORMED is the only advice.
You have made the first step by asking the questions.
Second follow the advice.
Third be prepared before taking the responsibility, i.e. books and/or other research.
Fourth have a back-up plan.

We as fish owner have a responsibility to take care of these fish, to give them a good home, with clean water, the right food, and the right conditions so they can live a good life.
