that Lotus sent me to to figure out my high ph and it mentioned
"The consequences for fish are many and varied. It affects their breathing ability. High acidity or alkalinity can cause direct physical damage to skin, gills and eyes. Prolonged exposure to sub-lethal pH levels can cause stress, increase mucus production and encourage epithelial hyperplasia (thickening of the skin or gill epithelia) with sometimes-fatal consequences."
I don't know if this helps or not or if the fish got better.
