I have 3 F8 puffers. One of them however, seems to be acting sickly; with that said, I'm not sure if I'm just being paranoid. I noticed a complete change in behavior yesterday. I've had these guys for a little over a year. He has been putzing around in the bottom of the tank, much like he's sleeping, but this is constantly, even during the day. But, if I give him a nudge he'll get up and swim about, though his swimming patterns aren't even normal. They're very slow [think as if he didn't give a damn about what was bothering him] and at times he'd just get up, move to a new spot, and lay down again. He sways side to side with the current of the water. His mouth seems swollen compared to the others [I've tried to take clear photos of this, but he's small (~1") and to get a clear picture is difficult with him lying in the center of the tank and all], the bottom of his mouth in particular so I'm also very worried he's not eating. He's relatively thin [certainly thinner than my other 2] but it doesn't look like a sickly thin [as some of the ones I've seen on here]. I haven't seen him eat in the past day, but then again I haven't even seen him swim to the surface of the tank. He used to be very lively and dart all over the place so I don't know what's wrong. In the past 5 hours I've placed him in his own 5gallon tank to see if I could monitor him better. As of right now, he is moving about, but it's still sluggish and he lets the current move him [as in, when he's near the part where the water is coming out of he lets it push him down to the bottom of the tank before trying to swim up again.. is he just trying to have some sh*ts and giggles with me or what...
Nitrite: 0
Ammonia: 0
Nitrate: between 0-20 [closer to 0]
SG: between 1.000 and 1.001
pH:7
The only thing that has gone wrong in my 10G tank is that it's invaded with algae quite a bit. I clean it off the same time I do water changes, but it comes back with a vengance.
I know this was long winded but I wanted to provide much detail as possible so maybe someone could help me. After a year of having all three [they were all purchased at the same time- I cleaned out my LFS getting these lil guys], it would be very sad to both me and the other 2 if we lost him.
Included are some pics here-
This is what he was like initially:
