Travis McElroy Instagram – So, two days ago I noticed this white discoloration on the side of Roy, my angelfish. Does anyone know if it is an indication of illness? Stress? Is it marks from another fish?
Additional Details: There are no new fish in the aquarium. I did some rearranging of plants and some cleaning that might have caused stress? | Posted on 12/Jul/2023 18:26:26
