Fish Fanatic
I think it would be good to do a second tank for the weak one, place him in it with a very gentle sponge filter.
Keep water super clean and feed him good foods. He may bounce back, but at the very least will make him more comfortable.
You can seed a sponge filter using a bit of filter media from your main tank. Place it inside the strainer of the sponge filter, so you dont lose the cycle.
Transfer half the water in the new tank from the old tank.
I do appreciate some of your suggestions but you think he can bounce back then I guess you don't really understand DGD. You claim to be an expert on dwarf gouramis telling me that both are males lol. when I already told you they built a nest together with bubbles and laid eggs and my German Rams ate the eggs.
There is nothing I can do other than make this fish camo a peaceful place to die. Even if I put him back in the main tank none of my fish will pick on him but he will continue to be sucked into the intake valves because he's a very weak swimmer now. Thank you for the suggestions I just want to make this fish comfortable. My father would have just flush him down the toilet lol back in the 1970 when I first got involved in the hobby with him.
