There's so much information on aquarium salt, but I'm having more trouble finding anything on epsom salt (even on this forum).
I know the chemical differences, what I'm looking for is what exactly each treats and how much epsom to use. It seems to be agreed that aquarium salt is a tsp per gallon, but for epsom I've seen everything from 1/8tsp per gallon to 3tsp per gallon.
I'm asking because I'm not entirely certain what is wrong with my fish, and figured that a salt bath or just adding a bit to his tank would be a good way to try and treat him without jumping to every medication out there. I posted a thread
a little while ago showing concern, but nothing seemed to be wrong so I let it go. Over the past two days it's gotten to the point where all my fish does is lay on the bottom of the tank, usually on his side, occasionally coming up for air. He doesn't look bloated but he won't eat. His color also doesn't seem any paler and his fins (from what I can tell since he isn't swimming much) are intact.
