I noticed yesterday that my puffers (2 Ceylons, in 20 Gal tank, will upgrade to at least 100gal in a couple months) have little white shiny dots on their caudal fins (they look a bit like scales on "regular" fish). I'm not sure if they're raised, and only one of them will come up to the glass when I'm there. The other one's a little on the shy side and will come to the glass to get a better look if I'm farther away. Since the white dots are really small, and not sure if they're raised, I'm going on other symptoms to diagnose them.
They're really agitated lately, taking quick little sprints once in a while, and wiggling their caudal fins a lot more than usual. They were a little darker this morning and more agitated than usual, so I'm a little worried. I think I even caught one of them trying to rub up against one of the ornaments in the tank, but I can't be sure. They seemed ok when I went to test the water just now. The little white specs seem more like long white strands now on their caudal fin?
Edit: Water parameters:
nitrite: 0.3mg/l
nitrate: 0mg/l
ammonia 0mg/l
pH: 7.0-7.5 (will be raised after cycling)
kH: 5 dkh (will also be raised after cycling)
sg: 1.000-1.001 (was 1.002 until the emergency water change a couple days ago)
temp: 27-28C, 82-84F
As for water changes, because of a power outage (again, due to weather), their water temperature dropped down to 20C (72F, i think?) a couple days ago (Friday). When I found them, I panicked, and put in 2 gal of hot, conditioned tap water, without any salt, as it wouldn't have had time to dissolve. I managed to get the water temperature to about 22C, and by adding more conditioned hot water, managed to keep it around there until the power came back on later that day.
We also recently put in a couple of new decorations, as they seemed to be getting bored, and an air stone just in case, since the water temp is usually around 27C (82F?).
I can't really remember what else I was supposed to put...but I'll check back after doing some water tests. Unfortunately, we are cycling the tank with the fish in the water, as we didn't have enough time to do a fishless cycle, and I have no spare tank available to quarantine them at the moment. Hopefully it's not because of that...*nervous*...
Food: frozen brine shrimp and frozen blood worms. We're working breeding snails for them. And may give them some prawn tails and clam shells to let them wear down their teeth in the mean time.
I've had them at home for about a week, and have put some water and yarn from their previous tank to help with the cycling.
I can't remember anything else for now, hopefully someone can help. Maybe it's just the decorations? Any help would appreciated, hopefully this wasn't too long to deter people from reading the whole thing
