My RTC has developed a problem around his gills mainly on the right hand side , he's lost his appetite and is really lethargic sitting at the bottom of the tank with his dorsal fin clamped, also the top of his head has gone prune like as if he's dehydrated????? help please.
Just to be on the safe side you may want to add some sort of ammonia de-tox like Seachem's Prime or something similar.
You might want to consult with necrocanis, but I would add some salt and a broad spectrum bacterial med like Maracyn plus or Melafix.
I would REALLY like to see an ammonia test to be safe though.
I won't get a chance tonight but first thing tomorrow I'll go to my local shop to get a test and some ammonia de-tox and post the result. added Melafix too 65ml of it.
looks like gill flair it is usually because of poor water quality a pet shop in alabama has one with that. I would do a good water change raise the salt level and throw in melafix. also if you have a big aquarium go to the pond chemicals and they have a pond melafix that treats 1600 gallons for about the same price as regular melafix
