I am new to Kokos and have recently been learning a lot about goldfish as this is the first time my fish has gotten sick.
I believe my fish may have mouth rot, but am not too sure.
I currently am treating it with Microbe Lift Artemiss Freshwater and Saltwater (recommended by someone at Petco). I have aquarium salt, and have slightly salted the aquarium (about a tspoon) but have not tried a salt dip (I've never done one and am scared too lol). I've also been reading a little too many blogs and posts and have become slightly confused as to how to approach treatment.
I know I haven't been treating him for too long, however, I'm super worried, as I do not want the condition to worsen, and I haven't been seeing it get better.
A little backstory: I won this fish at a carnival while in high school, and have a 20 gallon tank with a basic carbon filter (with the little extra sponge to reduce ammonia), a basic heater, and oxygen going through the tank, I've never, until recently, measured the pH or was concerned about ammonia or anything because I've never seen him get sick. Fast forward to about a month ago, his original filter had broken, and I did a terrible thing and did not get a new one until about a week ago (I know, I'm horrible). I noticed a little swelling above his mouth, and figured it would go away, but now it has gotten worse and I am really worried and need some help.
I recently took some measures and his water conditions seem okay (according to some of the internet):
Test Results for the Following:
* Ammonia Level(Tank): Not sure
* Nitrite Level(Tank): 0 ppm
* Nitrate level(Tank) 200 ppm
* Ammonia Level(Tap): ?
* Nitrite Level(Tap): ?
* Nitrate level(Tap): ?
* Ph Level, Tank (If possible, KH, GH and chloramines): 7.0 ph; KH: 40; GH: 180 (I know it's super high, but it's been his norm since I won him at a fair)
* Ph Level, Tap (If possible, KH, GH and chloramines)
Other Required Info:
* Brand of test-kit used and whether strips or drops? API 5 in 1 testing kit
* Water temperature? Around 78 degrees
* Tank size (how many gals.) and how long has it been running? 20 gallons (I know, I need to make it bigger, I've just been changing the tank size slowly as the fish gets bigger, but right now he's sick)
* What is the name and "size of the filter"(s)? It's a 30 gallon filter (cause the 20 gallon one broke and wasn't the best), Aqueon Quiet flow
* How often do you change the water and how much? 25% change about once a week or week and a half, 50% change once a month
* How many days ago was the last water change and how much did you change? 2 days ago, 20%; filter has been turned off due to current medication
* How many fish in the tank and their size? 1 goldfish, 20 gallons
* What kind of water additives or conditioners? Safestart and Goldfish Protect; Currently some aquarium salt as well
* What do you feed your fish and how often? Tetra Goldfish Vitamin C Enhanced Fish flakes; Once or Twice a day
* Any new fish added to the tank? No
* Any medications added to the tank? Microbe Lift Artemiss Freshwater and Saltwater
* List entire medication/treatment history for fish and tank. Microbe Lift Artemiss Freshwater and Saltwater 5 days; a little less than 1 tspn a day
* Any unusual findings on the fish such as "grains of salt," bloody streaks, frayed fins or fungus? See photo - the rest of his body looks fine, just that mouth area and eye; but mouth is my biggest concern at the moment
* Any unusual behavior like staying at the bottom, not eating, etc.? Some. Without the filter, he doesn't seem to realize when he's getting fed (he used to be able to recognize when I was right about to feed him, and would just eat the flakes in the water as they were pushed down by the filter. Now when I feed him, he doesn't float to the top to eat :( (so this has been going on for about 5 days). He waits for everything to sink to the bottom). Additionally, for the first few days, he was hanging out at the top corner of his tank, but now he is swimming around, back to normal). I took out most of the small plants and decorations that might be able to hurt his mouth (since I read that with mouth rot fish will try to scratch themselves).
