Fish in the aquarium: 1 Betta splendens, 5 Panda, 1 Ancistrus.So I think we might have 4 options;
NOTE that symptoms do not have to indicate a disease, merely a reaction to something that is not a pathogen.
- A nasty case of lymphocystitis virus.
- Fatty lumps from a less-than-perfect diet.
- Excess mucous, from something in the water irritating the fish.
- Cancerous tumours.
If bacteria/fungus was involved and/or the immune system of the fish had been compromised, then aquarium salt would assist.
A dose of 1 tablespoon per 5 Imperial Gallon would be a suggested dosage, to begin with. Normally, a therapeutic dose would be 1tbsp per 3 Imp.Gal., but care has to be taken with some Corys.
IF it's the virus or any other pathogen, then your other fish, whilst looking healthy at the moment, will likely have it.
Aquarium salt is a lot safer than adding medications, without knowing exactly what it is we're adding medications for.
Salt won't hurt other fish ?!
