Looks like skin irritation from either pick or water quality. I can see image but not video
Thank you- now I see itHere’s a pic too
May be insufficient- what are dimensions?
I agree with @vetteguy53081 This requires immediate treatment - and has the potential for significant worsening. A hang on thing (I think you mean an acclimation box??) will not work. I suppose in a pinch you could use reef rally pro which has some antibacterial components, but may not be enough.
Seems like If you used your tank water, it would be less stressful - and you get a 'free' water change.
Fresh sterile water same salinity as display tank
First. If the fish is not eating, one doesn't know exactly what dose they are getting - or if they are overeating, etc etc. Second - the lesion Is on the skin - and probably - the best way to attack is in the water - and realize also that fish will take in antibiotics internally when 'breathing'. the reason kanamycin and neomycin are not used much anymore (nor their relatives) - is that they can be toxic. In humans they are not absorbed orally. I would use the 'in the water' method:)
Most bite marks heal better in low stress environments.
Kanamycin is not an oral antibiotic.
Garlic is an immune system booster and not remedy. As for clean water, you are avoiding any possibility of foreign bodies in the water affecting the the would. If tank is fish only, you can treat direct but unfamiliar tank does not impose stress and with all the persons out there utilizing quarantine systems, stress is often not a factor- disease itself is
Kanaplex is kanamyacin based and acceptable as it’s absorbed by fish internally and externally
kanaplex is kanamycin - though Its some sort of blend. In any case, the same conclusion (IMHO) is warranted - which is - dosing through feeding it not a good idea
