Great news... my Fishy is getting better. Swelling way down, bubble on belly shrinking able to swim on the bottom again, it's a miracle. Going to continue to fast him, and use the maracyn two and epsom salt.
It should be fine since you will need at least a 75-100g tank to house the GKF for the first year or two, however, you would be taking a risk.....honestly I wouldn't recommend it.....
Good to hear the fish is better
My fry are growing fast soon to go to market at the end of the month
Sometimes aquarium salt can make swelling problems worse-it all depends on what the cause of the popeye was to start-you can usually pick up Epson salt for less than 3-4 bucks at most store with a pharmacy dept or if you have an older neighbor...ask them...it is used in humans for foot soaks, aches and pains, laxative, general tonic type stuff or someone that gardens a lot it is used for flowering shrub, lawns etc.....they may have some...all you need is a tsp or so......
I like to use the Epsom salt 1tsp/gal 10 day treatment along with the daily 100% water changes and if it is related to an injury I will use the Epsom salt until the swelling goes down and switch to aquarium salt to complete the 10 day treatment.
Anything with swelling I use Epsom salt 1tsp/gal up to 3tsp/gal-injuries I like to use aquarium salt 1tsp/gal up to 3tsp/gal (in salt tolerant fish) both I do 100% daily water changes-treatment is best done in small QT
Depending on how bad or why--I add oak leaf to the water-IAL will work too
