My water is Tests great and my salinity is 1.030. He ate well the day before and when i got home from work getting ready to feed him i saw he was stuck to the filter
She said they arrived in brakish water but she put him in freash water till i picked him up later that day and that was a almost two months ago. Its like he died cor no reason
Maybe he meant 1.003, which could potentially be too low. I have never been able to keep a gsp alive (I've had 2), the longest I've had one was 3 months, seems its hard to figure out the salinity on these guys, or maybe since mine always came from walmart they were mishandled previously.
A SG of 1.003 shouldn't kill a GSP.
There are definitely other factors going in in either the care or source of these puffer failures. Walmart is a poor source for any fish.
