Def. add some vitamins to the algae sheets, and you can add some to the tank water too. My yellow started to loose his fins along with HLLE too. I tried everything from removing my carbon, stepping up maintenance, etc. what all the sites say, and nothing seemed to help. Then I read this on the doctors site (it mainly talked about cichlids and this disease) and tried it, Even though it says conditionally effective, and within 24hrs, all pale spots around his face were yellow again!
Head and Lateral Line Erosion (HLLE) or Hexamitiasis, this condition is still poorly understood. Many believe the causes are poor
water quality and a lack of
vitamins A and C. In most cases, the etiology (cause) is probably an internal normally harmless parasite, Hexamita, which lives in the fish's stomach. The hallmark of this disease is erosion of the pores along the front and side of the head.It is believed that when the fish are stressed and weakened from
vitamin deficiencies, poor quality
food, and/or poor water quality or other stressors, the Hexamita migrate through the fish's system. The sensory pores (on the front and the side of the head) become pus-filled if the microbes migrate to these locations. If the parasite invades a vital organ, death follows. Since the fish's immune system is already compromised by the Hexamitiasis, serious illness may also result from the secondary invasion of bacteria or other parasites.
Treatment is only conditionally effective using
metronidazole. It is very important to treat all fish from an infected aquarium whether or not all are showing outwards signs or symptoms. Follow label directions carefully and provide fish with a stress-free environment, high quality food, and vitamin supplementation to help increase the fishes' appetites
SO I DONT KNOW IF THIS WILL HELP YOU OR NOT, JUST SOME INFO I THOUGHT I WOULD SHARE.....
