We feed flake food in the am and frozen shrimp (mysis or brine) in the pm.
First thing is to try and get those nitrates down some with a few good sized water changes using well aged/aerated SW
. By reducing the DOC
/nutrient, you help starve the bacteria feeding the problem.
As far as feeding, you need to reduce that to once a day or every second day. Fish do not need feeding twice daily or even daily for that matter. Also be sure the foods you feed have the proper nutrition the fish needs to promote a healthy immune system. Flake and mysis can be okay but brine won't be unless gut loaded or fortified. I would be sure to start adding some type of vitamin to the mix and possibley making your own foods.
Increasing foods nutritional values and reducing nutrient within the water column are often all that is needed for minor problems.Unless a true fungal infection, then it will require treatment but it's best to start with what I've mentioned above. It is not life threatening as a rule so you have time to try this first.
What is a a gram negative antibiotic? I can't use Melafix?
I wouldn't personally bother with the Melafix. It can help with preventing wounds from becoming worse but typically not good choices in terms of a cure. It won't hurt anything (primarily tea tree oil) if you do decide to add it to the system but fair warning, it tends to make a mess. Any external equipment will become coated and work less efficiently, the skimmer will need to be turned off, all carbon/resin products removed and you will be a few weeks getting rid of it after treatment is done.
Bacterial infections are either gram positive or gram negative in nature. When it comes to SW
, 99.99% will be gram negative in so you need to be sure if treatment is needed, you have the right medication to do the job.
Maracyn II at double the recommended dosage added daily for 7 days or Furacyn (nitrofurazone) used as a single dose of 30mg/gal
and left for 3-5 days total. If after a week or so you do not see a reduction in the size of the affected area, you should consider treatment. Hopefully you already have a the QT
equip needed and are cycling to be on the safe side.
