May I ask why the temp needs to be turned down?mate, i know what is wrong. unless it was the case that the fish went on its side during transport and has not been able to right itself since then.. but i think this is not the case.
you dont add epsom salts. epsom is one salt harvested from the town of epsom in england.
the fish has been shocked by a sudden change in water or it is showing toxicity to something.
you need to add mineral salts. harder water! turn the temp down!!! slowly let it drop.
this is if your fish is still alive. it can die within 2 days like this.
then get some agricultural lime, add just 1 gram per hundred litres of tank water.
or calcium carbonate from the fish shop. or you can use dolomite lime just the same, it has two forms of minerals.. magnesium and calcium and this is preferable i think.
i also suggest you add 5 grams of rock salt per hundred litres. not table salt because it is just one form of salt. this is not much, but enough to help the fishes cells get back into a balance.
you can also use geo liquid. this has stuff in there from the earth just the same.
now tell us, where do you get your water from?
is it rain water only and too pure? or is it the exact same source water your friend used.
call him and ask and then get back to me.
oh and dont you feed that fish either. it can go weeks or months without food. never feed a sick arow that is big. it just dont need food and will make it worse. i have seen this happen before. 1 died, 1 lived.
The water is directly from the tap, but I've added dechlorinator to the water when doing water change.. My friend's water source is from tap too..
How long before I should feed it again?
