The tank is a 30 litre tank i have had them for around a month, i don't know the water parameters and they where eatting before
I checked them the next day and the where happy swimming and eatting fine
they have no tank mates its just the three of them
Hey i have three dwarf puffers i have just come home to feed them but they wont eat,two will hardly swim around and the other is just sat at the bottom of the tank only moving his eyes and it also looks like it has puffed up a few times.
