The Puffer Forum

Hello,

I bought a new little puffer, but it's tree days and he doesin't eat. I don't know what to do... I have another big one and it's no problem with feading.
This little ones belly is darkened. Please hepl me...

What puffer?
How many gallon?
Can you answer these for us?

1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.

2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.

3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)

4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.

5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.

We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.

What puffer?
What are you feeding him?
What size tank?
We can't help you until you answer all the questions in red.

Oh sorry.

It's Tetraodon nigroviridis.
My tank is quite little about 7 gallons. There lives two tetreodons and to Chromobotia macracanthus.
I don't know the wather parameters, i change half of wather after 3weeks. I use just some neutralizer that clears the wather. The aquarium is about 8 months old. Didin't change anything just bought this little guy. I fead them with frozen food and dry granulated food (moisted)
Sorry for my english, i know its bad

Oh wow. You need to get a much larger tank fast. One of those fish needs 30 gallons to itself! You need to learn how to take care of a tank before purchasing such a beautiful fish. Please think about giving up your fish to a local fish store so that they can be properly taken care of.
Your fish are VERY stressed out right now, and that is why the other one isn't eating. Your tank is overly populated. You know that a Chromobotia macracanthus can grow to be 16 inches long, right?

They need 30 gallons each.
There brackish fish then go into full marine.
Get a test kit now.
What is there diet?
The tank is way overstocked

And please, seriously think about giving back the fish to a local fish store that is not Walmart. They will die under your care if you don't get a 60 gallon PLUS high end brackish/marine tank set up for them soon.

This is all true. Some fish stores will board your fish until you get a new aquarium set up. Please read the article in the Library about emergency cycling; this will help you to understand what's going on.
