Oh man, those ears are just the cutest...I'm in love!
Getting a voltmeter today and will get a grounding probe as well. Removed the Carbon even though it's ROX. Was wondering if the ALK changes could have caused it?Purchase a titanium grounding probe either way. Less than $20 on Amazon. There are YouTube videos that show how to test.
While Nori is a good supplement, it is not a total diet. In addition to nori, feed at minimum:Our new sailfin is developing it. Haven't feed him Nori every day but have been feeding it often and have always had a stray volt probe in the sump. I guess I need to look how to test the water for voltage and see if maybe my probe is bad. And make sure to feed vitamin soaked Nori every day.
Only fish we've had develop it are both the sailfins
While Nori is a good supplement, it is not a total diet. In addition to nori, feed at minimum:
Spirulina brine shrimp
plankton
Mysis shrimp
LRS Herbivore diet
Formula 2 frozen and flake
Add selcon vitamin and garlic to your foods.
Nowadays, are we still with the same info on HLLE causes? Are any of you aware of any new concepts? Viral causes? Infeccious? Any other new info about this disease?
Ah, one of my favorite topics! There seem to be three different types: FW HLLE, like you see in discus and oscars. That has some connection to internal parasites (Hexamita or Spironucleus). Then, there is "epithelial thinning" mostly seen in freshwater fish such as walleye, but also seen in groupers. That may be related to chronic heavy metal toxicity. Then, there is the "classic" marine HLLE, as seen in angels, surgeonfish, etc. The following applies only to the latter:
Nobody has ever demonstrated transfer of HLLE from one fish to another in a manner that suggests that it is a contagious disease. Stray voltage is a red herring - people have fish with HLLE, and then detect stray voltage and conclude that was the cause. The vitamin C angle was based on a flawed "study" back in the 1980's. Even copper usage is suspect - too many copper treatments end with carbon filtration. Here is the abstract from my 20112 study:
Abstract
Head and lateral line erosion (HLLE) is an acute or chronic,
often progressive problem affecting captive fishes. Its etiology is
enigmatic. This study examined the relationship between the use of
activated carbon as a filtrant and the development of HLLE lesions
in ocean surgeons Acanthurus bahianus. Three identical, 454-L
marine aquarium systems were established. Thirty-five ocean surgeons
were distributed among the three aquarium systems. Activated
lignite carbon was added to one system, and pelleted carbon
was added to the second system. The fish in the third system were
not exposed to any carbon. All 12 fish that were exposed to lignite
carbon developed severe HLLE within 3 months. The 12 fish
that were exposed to pelleted carbon did not develop gross symptoms,
but microscopic lesions were discovered upon histological
examination. The 11 control fish did not develop any visible or microscopic
lesions. Based on these results, the use of activated lignite
carbon in marine aquariums that house HLLE-susceptible species
is discouraged.

I rescued a scopas tang very similar to this picture, the fins are missing. Will they ever grow back?
