Hello everyone, Just curious what might be on my watchman goby’s mouth area? It’s also behind his fin on the right side of his body, he doesn’t seem to be acting off or lethargic at all, he’s eating normally, here’s some photos I got, might be hard to see but it’s there. Thanks.
looks like it might be mouth rot. From what I've read from @Humblefish he recommends Furan-2 + API Triple Sulfa (or Seachem Sulfaplex) instead of furan-2 and kanaplex.
