Hi, I've been keeping two fire sals for about 6 months an have had no probs with them at all. They've been visible more than I thought an have great characters. Until I noticed one not very active or eating much which is unusual I had a closer look and noticed one had a gungky white substance on one eye which is slightly shut an looking uncomfortable. I no it could be anything just hoping anyone has any idea or experience with this?? Any help much appreciated. Thanks.
