If he's a bit skinny it might be worthwhile treating with paracleanse do two full courses of treatment 2weeks apart @ChillFish

I would add a small amount of aquarium salt 1 table spoon for 10 gallons that will aid Gill function and aid Gill function and add essential electrolytes I would also add an extra air stone have you noticed any rapid breathing hanging near the surface flashing spitting food out weight loss @ChillFish

Levamisole basically paralyzes the worms making it easy for your fish to Expel the parasites it will kill some that's why it requires a minimum of 4 weeks of treatment with levamisole they shouldn't harm your benefial bacterial with any medication theirs always I small chance it will I don't sterilise my filter the medication should deal with all the parasites if you dose correctly @Odd Duckhas a very effective treatment protocol for parasitic infections @MomOfEight

That what am thinking I don't think that's camallanus worms I think it's poop with the colour of the last food they had before you got them @Sherry

if it's nerite snails they will be fine with salt and metroplex in food mystery snails can be sensitive to salt so I would recommend removing them if Malaysia trumpet or bladder snails I would worry they will be fine

Have you been feeding them with a food that could make their poop red @Sherry

What I would is do is reduced feeding to only once a day for the frist week test daily during the Frist two weeks if you notice any ammonia or nitrite do a 50% water change and add a double dose of prime or Fritz complete to help detoxify any ammonia and nitrite

It's difficult to tell off your pictures could be the start of hole in the head if it were you would want to treat with metroplex in food feeding a small amount twice a day for upto 3 weeks if you don't have live plants I would start with aquarium salt 1 table spoon for 3 gallons for one week if the you notice more small pits or receding skin around the lateral line than I would treat with metroplex following the recipe I provided @Jenna321

It could be something in the bricks raising your pH kH and GH I would remove them and do small water changes to gradually get your pH back to your normal range @Goosedub

The only reason I keep it is to feed my goldfish I wouldn't use it in my other tanks as nothing eats it and and having to remove it is pain

Repashy shrimp souffle is used for shrimp

Could be an injury caused by fighting I would add some aquarium salt 1 table spoon for 3 gallons and monitor for the next couple days if it's start to get worse then I would consider doing a course of kanaplex or maracyn2

Looks like your starting to get some pineconing what I would suggest as you have done two course of kanaplex is do a course of metroplex in food feeding a small amount twice a day for upto 3 weeks and do the Epsom salt baths as pineconing can be a sign of something internal going on like polycystic kidney disease or internal bacterial infection causing fluid buildup the salt will help reduce the fluid buildup @BilboMom

It's a Giant Colombian ramshorn snail they can be very prolific lay about 200 eggs a time

Bacterial Gill infection can cause bright red Gill's or ammonia poisoning if your water parameters are fine I would quarantine and do a course of kanaplex or maracyn2 and add some aquarium salt 1 table spoon for 3 gallons @BAT

If it's constipation you want to 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 with constipation you can add Epsom salt to his tank but it will raise your GH and I would feed daphnia or brine shrimp they can help with the bloating @BilboMom

What I would suggest is treating with API fungus cure and leave the salt in for another week

@GardenStateGoldfishhas a lot of experience maybe he can chip in

What I would do is add a small amount of aquarium salt 1 table spoon for 10 gallons at that level it won't harm your plants and I would do two full courses of paracleanse two weeks apart

Turbidity of the skin can be caused by a number of things a parasitic infections poor water quality what are your water parameters @iadala

The combination of the two provides a more broad spectrum antibiotic treatment that treats gram negative and some gram positive bacterial infections the best treatment for more severe bacterial infections like columnaris

From what I have read API general cure is fine to use with scaleless fish @t fishguy

With the symptoms your describing I think your dealing with fast moving bacterial infection with the colour loss disintegrating fins what I would do is treat with a combination of kanaplex and jungal fungus clear fizz tabs containing nitrofurazone following this treatment plan

Good to hear there all improving

Dither fish might distract him and allow his fins to heal as long as you have another tank to put the fish in if it doesn't work out
