DESPERATE FISH REHOMING please help

I have two celestial pearl danios and one emerald dwarf. Unfortunately the rest of them got sick a few months ago, it got better and now I just had to euthanize another this time due to dropsy. I dont want them to suffer theres only 3 left and all males so they are always sparring. I cant afford to get more and they deserve a better life. Im located in international district. Id like to keep my tank and try to re-establish it but I have medicial salt for them and I will give that too. Please someone help my babies. Ive had them many years and I just dont want them to suffer. Im in international district near little Saigon
