The Puffer Forum

I have two golden/bronze puffers for about a month now and they have been doing fine til a day or two ago. One of them is just seems to have less energy. I fed them some blood worms and they both were very attentive and ate until their bellies were full! The other one is swimming around after eating while the 'wierd acting' one just went back to swimming in place under an anubias plant or next to the java fern switching spots of not as active as the other one. I added a 5 inch peacock eel a day ago but the puffers symptoms seemed to have started a day or two before adding the eel. The water conditions are 1-2ppm Nitrate, 0ppm nitrite, 0ppm chlorine. pH~7.7 I just did a 25% water clean two days ago and have been doing weekly 25% water changes. There are two little danios in there that have been in there for months and the tank has been running for 2 and a half months. There is a little plexiglass box with 7 small ghost shrimp in it for the puffers to eat when i take them out of the little box.
the tank is a 55 gallon fresh water tank with a 200 gph and an aquaclear 70 300gph filter on them.
Any thoughtS? Maybe its just being lazy these last days or so? I'll add some pictures soon
also looks like puffer is breathing a little harder than the other one.

Could be nothing to worry about. My modestus spends most of his day camped out underneath the heater, yet he's seemingly healthy and growing larger.

After a good meal my puffs will start breathing heavy, they will also go to their favorite place in the tank and take a day long nap.
Is it just after you feed them that they act strange? Or is it all the time?
