Hello guys, 

my name is Daniel and i am from germany. Pls excuse me for my bad english, but i try my best.

I try to breed the puffer fish too. Currently I managed to get 7 of him big on the first try. These are now 8 weeks old. On my second attempt, I only got 2 large larvae out of over 300, they are now 4 weeks old. I also feed parameciums in lagre quantities, but i think that still wasn´t enough. Do you habe a trick for geeding a lot, wihtout polutuing the water too much? The pichtures shows how i try to breed them.

Hallo, ich lebe in der Schweiz! 
Mountaintoppufferkeeper züchtet Artemien für seine jungen Puffern. Machen Sie auch das?

Hallo, ja das mache ich auch. In großen mengen sogar. Aber was ich bis jetzt feststellen konnte ist, das die Fische erst nach frühestens 15-20 Tagen Artemien fressen. Ich habe das Problem davor, das mit in dieser Zeit die meisten versterben.

So Matthew Proctor, who you know here as @mountaintoppufferkeeper, wrote an interesting article in Amazonas magazine (Jan/Feb 2023 issue) on this very topic. In the article he describes his technique of slow water change and filtration. That's all I can say because I don't want to speak out of turn. If you can get hold of a copy it should help.

thanks for the mention @DaveO. @DanielBlub i like to use a floating ring like you have in a bigger tank to keep the water quality up between water changes, I use polyfilter cubes, that change color based off of what they absorb, to see how the water is doing daily.

I dont think I can feed enough paramecium to grow large numbers of spotted congo fry past 5 days but i do think I can make enough infusoria and paramecium to feed them for the firat 14 days. 

I feed the baby puffers paranecium 2-3 times a day and feed infusoria at the same time. That seems to keep the food around the puffer fry longer especially if my light source is somewhat concentrated on the sides of the ring.

I squeeze out a sponge filter from the adult puffer tank into a glass jar to start my infusoria culture. 

Grindal worms have also been helpful i culture those on scrubber pads and dog kibble. 

I feed the larger fry whiteworms i also grow on scrubber pads and kibble.

Thank you mountaintoppufferkeeper 

About the polyfilter, is this the sponge who change his color if it dedects nitrit? If yes, i know waht u mean, and this is a good idea.

You talk abaut waterchange, how many waterchange are u doing and how much % did you do each?

I tend to run a large amount of live plants in my puffer tanks to help keep the water cleaner and grow that infusoria and other small foods. 

Yes the color change polyfilter . I cut it into small cubes and judge the water quality visually. For me it is just a little insurance between water changes.

I am mostly using it for Organic Wastes: which it absorbs as itchanges to light tan and progresses to dark brown. For me it has been extremely helpful. 

I probably change 25% of the main tank water a week and use airline to siphon out  any excess debris in the ring as needed daily being careful to avoid the puffer fry .

If my polyfilter changes color too fast would try 25% ever 3 days here. I do not want too much fluctuation in the parameters especially in their first few weeks of growth

THX for your informations. I orderd now exact this polyfilter.

I use 3 aquariums for my Puffers.

An 55 liter dennerle tank for the puffers who are 1cm+, and 2 "IKEA Kallax" tanks wiht 25Liters for the eggs and jung puffers (check pictures). 

But i can´t find the error, why only 2 for 300 puffers survived in my last try. I use extrem clan water from an osmosis system, mixed with freshwater salt to get:

KH 3, (Carbonat)

GH 5 (overall hardness)

PH ~6,5 

NO2 0

~26°C

 .....

That looks amazing. I hatch in the ring and use that to contain the fry with the food for the first few weeks or more. 

 Initial days.... plants in ring20230407_050055_1.gif.83492023a012840761102a680e0c253f.gif

More advanced... still in ring

i waited until they were eating grindal worms and trying the bigger whiteworms to release my last batch into the 20 gallon / 75 liter. If i keep them full to brineshrimp and grindal worm size, which is generally at a few weeks old, they seem to all make it

Updating this thread to keep it all together.Spotted congo puffer project continues.

I spent some time after the last lesrning experience coming up with a better design to get scatterer puffers to "collect their own eggs for me" and after some refinement with an expert in fish 3D printed items this pedestal was the first version we came up with from the fish lab.

Turns out I did design it properly and was "thinking like a puffer". She was eating her eggs during this. My opinion is it looks a little more intense to us than it is for her. You can also note she holds standard patterning here no stress patterns at all:

Tried snagging the eggs that missed with my no drip baster/egg retriever

This is the result of the 1 collection today. MB in the coop specimine container hanging inside a 20gallon.

Did u use the polyfilter only as an idicator for the water quality or put u more in the tank to get a better water quality?

I use the polyfilter to get a visual indicator of the conditions the fry are in. For me it is more of insurance. It gives the visual indicator so I know how the water is for the fry quickly

Greetings from Germany,
Here are pictures from my last breeding attempt. I grew 200 puffer fish.
 They are born on 14 March 2024

Nice. They are a fun puffer. Those photos awesome. Im always curious how the milestones and growth changes for me up here at +/- 2,804 meters (9,200 ft) vs lower elevations.

how long were yours on paramecium sized foods?

I hope I understand you correctly. I have to feed them with paramecium for at least 10 days after hatching. Then the first fish start to eat brine shrimp. But not all of them, so I feed them paramecium for at least 3 weeks and also brine shrimp (plus banana worms etc.)

Yes. Thank you. That was what i was curious about. Your development time with them on food sizes vs my first run of spotted congos. That batch also took about 3 weeks to finish paramecium sized foods and get up to new baby brine

Day 4

Most likely first hatch eve 😁
