2) 29g with two GSPs , one knight goby
3) Feed frozen food, brine, mussels etc, water change usually every week with cycle, stress zyme
4) ugh read below
5) I've had the aquarium for over 2 years and never problems until...
Okay so I used to have two Mono fish, two gobies and two GSPs in my tank...and I was planning to upgrade to a much larger tank soon. Anyway, I tested the water and found out my nitrates where WAY too high and I decided to do tank changes much more, every other day until it got lower. Anyway, the next day, my big mono died suddenly...didn't look ill. Then the next day, the smaller mono died too! Shortly after, one of the knight gobies who didn't look well anyway, died. I was in shock and I was terrified for my puffers... they still looked fine but I noticed they wouldn't eat. Anyway the nitrates where still way too high. I think I was overfeeding them which led to that
Okay so puffy is doing okay, but still not eating. The other one, puffalicious... is the strangest puffer I have ever seen. After doing the water changes I noticed he kept going up to the top and gulping air and floating there, almost looking passed out or playing dead... and I had to "burp" him to get him to swim around again. I did this a bunch of times and then thought "well maybe he is puffing up, so I will leave him alone and maybe he will stop." Well this morning I found him rounder than ever, with his mouth up at the top of the tank, not even in the water, and just sitting there. I could have SWORN he was dead. So I stood there for 5 minutes holding him under water and gently massaging him and finally after seriously contemplating that he is done, he burped up a bunch of air and swam away!!
So...I have no clue what to do now. He is still at the top of the tank, wont eat and keeps "gulping air" and floating there. Puffy seems to be better, but still not eating. I am SO sad! I guess life got in the way and I didn't do enough water changes...or fed them too much, I don't know. I've had them for 2 years and it was hard to see the monos go, but the puffers are my little babies and it would be terrible if they went too!!
