Nitrate ~40-80 ppm
Ropefish scales are peeling away on his face, his eyes are white and I think the same thing is starting with another of the ropefish. Last night he started to bleed a little from his snout. Idk if it's a fungus or parasite. The two that are affected are hiding whilst the third is completely fine from what I can see.
All of this happened within 12hrs time.
Does anyone have a clue what could be happening??
