Help needed sick Archer fsh

after a little research
How to cure:
The concentration of mineral salts should be altered to suit a particular species. If osmotic shock occurs, this concordance should be exact and it should be established immediately. Newly-purchased fish if they are obviously affected should be transferred to the aquarium with appropriate chemical composition of water (for example, into a quarantine tank, where they should be kept for some time). Changing chemical composition of water in the main aquarium can cause osmotic shock in fish already living there.
Then change water in the quarantine tank so that its characteristics coincide with those in the main tank. This is done gradually, within 2-3 weeks. Only transfer can newly-acquired fish be transferred into the main aquarium.
If fish suffer from osmotic stress the concentration of dissolved salts should be changed gradually, within 1-2 weeks, so as to avoid osmotic
 
you shouldn't keep the archer with those fish. archers are brackish as far as i know and you cant just add salt to accommodate him it wont work u have to use marine salt, not aquarium salt there's a difference not sure what but there is.if you do do this you would then be compromising the lives of your other fish. your fish arnt completely compatible gold fish are cold water fish and should not be kept with tropical fish. you should really research your fish before you buy them.

Dead on! Not every fish is suited to live with every other fish, regardless of whether or mot they seem to get along.
 
ok, wow i had some dumb ideas.
i now have it in a quarintene tank in a breeding net.
the tank was filled with water from the tank it was in than moved to the new tank.

I also called the pet shop that it came from and they confirmed that it is in brackish water.


So if i slowly equalise the amount of salt that was in the tank at the petshop with what is in the quarintene tank, it is likly that the fish will become well again?

p.s. i will be setting up a 3 foot brackish tank if it gets better
 
Yep, but not so much as to shock the fish or just as importantly the beneficial bacteria. Most sources seem to suggest raising it 0.002 SG per week at most, with each water change. Some say per month but I would think that's a bit too conservative.

But keep in mind that you'll need 1) MARINE salt not aquarium salt which is just glorified table salt (NaCl). and 2) a hydrometer/refractometer to measure specific gravity.
