I will try to answer some questions.
We use test strips.
I have a toddler, so there is no set schedule for his water changes
. Sometimes it's once a week, sometimes it every other week. I try to do at least 30%.
He has his mouth open all the time, but I don't see anything fuzzy. He doesn't seem to be having any trouble breathing. There are 2 XP3s on the tank. A spray bar on one end & a single output that acts like a powerhead on the other. There is quite a bit of surface agitation.
We run a fish room of 30+ tanks, and only 2 of them are smaller than 75 gallons, so we don't use Prime. We use a powdered dechlorinator that we can buy in bulk. I'd have to ask my husband what it's called. it gets rid of Chlorine & Chloramines, it just doesn't have whatever additive Prime uses to help with the slime coat.
I know he needs a more varied diet. I need to get him some more snails too. Unfortunately we are out in the sticks, so what I can feed him has to come either from my grocery store or PetSmart. I don't think there are even any bait shops around here, so that makes crayfish prohibitively expensive, and snails a rare treat. I'll go to Petsmart this weekend & check their fridge for live earthworms. my grocery store often will get bags of live mussels in the shell with no seasonings added. I've been hoping this guy will get big enough to handle those ASAP. Nothing freaks me out more than the idea of having to do puffer dentistry.
Thanks for the compliments on him though. My husband has a tendancy to overfeed, when he's doing the feeding, so it is pretty surprising that the puffer isn't a fatty.
Anyway, we fasted again last night. His lips still look lumpy. He's done a bit of swimming around today, but still not quite acting his usual self, and is back to hanging out on the substrate.
