You could use a turkey baster soak up the food in it and then shoot it down to the area where the fish are, if they really are hungry they come and eat it, and they won’t starve, fish can go along time without food.
I think I will euthanize my fish, it’s really sad to see them all eaten up from the infection, most of there mouths are eaten away. I have otos and Cory’s in there they been through the same meds, do you guys think they are infected also?
