Hi all, I've had my fair share of ich outbreaks in the past so I know how to handle it, but this time I just want an opinion or two. I recent brought home a little red cap oranda. I have been in the process of setting up a new tank for the goldfish (40g) - I also have a black moor and a fantail. I moved them into their new tank today and noticed little 'flower' has some spots. The thing is, my black moor was digging around in the sand earlier and was covered in sand for a while. The oranda does look like its got ich but it *could* be sand? It's only been since today. Opinions please? I wanted to try treating with salt this time. I do have meds in the cupboard if I need them. I don't have aquarium sand though. I have pure rock salt ( as in no additives). Would the rock salt do? And I believe it's a 0.3% dose I need? 3tsp per 10g? Is that correct? Shall I wait to see if it goes overnight before starting a treatment or shall I assume it definitely is ich and treat immediately?
