not sure about the mucus thing but it makes sense, my fry feed ok on the red marlbourgh but they very rarely went to the pigeon blood, and had to make sure the tank is always light and dark objects removed with water level lowered till they found the parents in first few days as pigeonbloods don't darken and they tryed to latch onto the sponge filter. Its a good job they are domesticated discus and not in the wild as they would get totally lost in the dark waters lol.
