Sorry to hear that she didn't make it

What I would do is to start water changing out the salt leave 1 table spoon for 10 gallons what other medications do you have to hand did the vet give you a definitive diagnosis@Colette

Columnaris is an external bacterial infections there's not much benefit in adding the medication to food What I would do as you have shrimp is two full course of maracyn2 or API fin and body cure which ever one is more readily available back to back both medication are shrimp safe dosing the tank start treating as soon as possible and remove chemical filtration during treatment

Sorry late reply been travelling Meds can be stressful it could have just be weakened due to illness what I would do is add small amount of aquarium salt 1 table spoon for 10 gallons that will aid Gill function and add essential electrolytes if it survives till morning it might pull though

Possibly columnaris that's a gram negative bacterial infections that spreads more quickly at temperatures over 75 and can kill in 24hr to 7 days depending on the strain the most effective treatment I have found is kanaplex and jungal fungus clear fizz tabs containing nitrofurazone following this treatment plan it could have also just injured itself and scraped its back I would still air on the side of caution and treat if you have shrimp kanaplex can be harmful @Shrimpee

Do a 50% water change add active carbon to remove any remaining medication then do a course of kanaplex and jungal fungus clear fizz tabs after that give an update I would wait to see if kanaplex and jungal fungus does the trick before treating with anti-parasitic medication with can discuss this after the 5 day course of treatment

You could just fast all the fish in the tank for 5 days they will be fine or quarantine and fast if the bloating doesn't go down they could be egg bound for that you would want to treat with epsom salt baths 1 table spoon for 1 gallon for no more than 15 minutes for 5 days as Epsom salt acts as a muscle relaxant

What are your water parameters ammonia nitrite nitrate pH KH GH temperature any rapid breathing hanging out near the surface lethargy @Scaperoot

Could be full of eggs or fat due to over eating what I would do is fast for 5 days and monitor to see if the bloating goes down if it does then I would look at what your feeding and how often give an update after 5 days @PluckyD

NMultiple fish having dropsy like symptoms could be a parasitic infections that will kill fish gradually over a period of weeks or there's something off with your well water and it's affecting your fancy goldfish as they aren't as robust due to inbreeding what are your water parameters ammonia nitrite nitrate pH KH GH temperature can you post a picture of any fish showing symptoms any loss of appetite weight loss white stringy poop any Reddening to fins or body @Nikki

Could have a bacterial component the fact that it's spread to other fish over a two week period what I would do a course of kanaplex it's a broad spectrum antibiotic treatment if you have shrimp or snails I would treat with maracyn2 as kanaplex can be harmful to shrimp and some types of snails @Ventuxio

What are your water parameters just in case something off As it spread to other fish What I would do is treat with kanaplex and jungal fungus clear fizz tabs containing nitrofurazone following this treatment plan

Your water parameters are fine possible pH higher than you would want I don't think that would be causing the issue your seeing liverbears are prone parasitic infections first thing I would do is treat with levamisole active ingredient in expel p once a week for 4 weeks and go from there

Am struggling to see the lumps in the picture when did you notice the first lumps and how long before other fish developed them any loss of appetite rapid breathing hanging out near the surface lethargy @Ventuxio

I think it would be worthwhile keeping Epsom salt in his tank for another 5 days and do a course of kanaplex that's a broad spectrum antibiotic treatment what parasite medication were you using

Could be dropsy that can be caused by a number of things such as organ failure parasitic infections internal bacterial infections the most effective treatment I have found aquarium salt 1 table spoon for 1 gallon to help reduce fluid buildup dose the tank with kanaplex to treat any possible internal bacterial infections and do a course of metroplex in food feeding a small twice a day for upto 3 weeks @Cinnebuns

It could be a parasitic infection with sunken bellys for that you would want to treat with oddduck treatment protocol for parasitic infections levamisole is harmful to shrimp and snails I would remove them before treating

That looks like a prolapse to me I would do epsom salt baths 1 table spoon for 1 gallon for no more than 15 minutes for 5 days as Epsom salt acts as a muscle relaxant to help your fish reabsorb the prolapse @osint

what are your water parameters ammonia nitrite nitrate pH KH GH temperature any rapid breathing hanging out near the surface lethargy flashing spitting food out sunken belly white stringy poop red worms protruding from the anus @khongor

I would be very careful when you have had neon tetra disease it has been found in angelfish danio rasbora barbs guppies goldfish aquarium science.org has some good information on neon tetra disease @Fishoutawater

Possible injury looking at the pictures I would just monitor your other could have swim into something in the tank knocking it out then coming to that what it sound like to me

Redose ick X and and half a packet of maracyn daily for 7 days don't use paracleanse that medication won't have any effect and on fungal infections or possible secondary bacterial infections

Yes that's fine

You use one scoop of kanaplex and one scoop of focus they both come with a small scoop

Yes Fast for 5 days and epsom salt baths
