We are here to help and we have offered you the help we can. Order some food for your frog or release it so it can at least have a chance at a meal.
And we will continue helping if you would like us to do so, to set up tank properly, how to test/treat and more. But im sorry it just breaks my heart to hear about frog (any animal) suffering and owner that is making excuses... It is really sad.
Save one animal and it doesn't change the world, but it surely changes the world for that one animal!
