To be fair here, there is no outright cure for HLLE
, just theories on what is compromising their conditioning to cause it; I personally see it as a social stress response, which is just compounded by associated contributing factors such as social status, territorial boundaries, food limitations, etc. I've pulled tangs from tanks with horrible HLLE
and "cured" them in a QT (20g-90g) by themselves, only to release them back into their main system and eventually show signs of HLLE
all over again. I've seen tangs have better conditioning in "bare" tanks with no live rock and fake decor just as I have in full blown reefs...there is no singular pinpoint cause.
