Is there a tankmate in with him? I see what looks like aggression from the looks of tail and upper/lower dorsal.

Does look beat up to me as well.
Seems to be a lot going on here.
Your instructs were clear and IMO, very correct.

According to humblefish Formalin 37% is used to treat brook

2) 30-60 minute bath treatment: 0.6 ml per gallon, or 12 drops per gallon. Aerate vigorously and treat at this concentration for approximately 45 minutes. You can actually treat for a maximum of 60 minutes if the fish seems to be handling the bath fine, but cut it short (30 minutes) if breathing becomes too heavy.

These are other products which contain formaldehyde (e.g. Quick Cure, Aquarium Solutions Ich-X, Kordon Rid-Ich Plus), but because these contain less than 37% formaldehyde their effectiveness is difficult to predict.

Formalin is best administered in a bath solution for 30-45 minutes. The bath is best done in a large glass bowl or container, but a plastic bucket is fine as well. (However, keep in mind that plastic may absorb some of the medication and then leach it back out during future use.)

Temperature/pH/salinity of the bath water should match the tank the fish is coming from (and going into afterwards.) It is very important to heavily aerate the bath for at least 30 minutes before and also during treatment to compensate for oxygen depletion. The fish should be placed in a premixed bath solution. DO NOT add more formalin after the fish is already in the bath.

It is important to always transfer the fish into a new/sterile quarantine tank (QT) post bath. Returning the fish to the same tank you took him out of will just result in reinfection. It is also impossible to determine if just one formalin bath will result in 100% eradication of the pathogen you are trying to eliminate. Therefore, it is wise to do follow-up treatment in a QT:

1) Velvet: Copper or Chloroquine phosphate for 30 days.
2) Brook & Uronema: Metronidazole (e.g. Seachem Metroplex) or Chloroquine phosphate for 14 days.
3) Flukes & Black Ich: Prazipro or another formalin bath 5-7 days later.

It is also possible to achieve 100% eradication with repeat formalin baths, but it’s important to give the fish 48 hours to recuperate in-between baths. Post bath, always transfer the fish into a new/sterile QT to prevent reinfection. And observe closely for at least 30 days to be sure the fish is 100% disease-free.

I did a google search for Formalin 37% and it does not look like you will be able to get this shipped to you fast enough but maybe? Anyone know if there is a product that contains formalin at 37%? If not will Quick Cure, Aquarium Solutions Ich-X, Kordon Rid-Ich Plus work for Brook? If so you may be able to get one of these shipped next day air which I think you will have to do considering how fast brook can kill. Until it arrives maybe just do a RO bath once a day?

Do I really need it I think the sickness is gone I think it may need time to heal unless I’m totally wrong on this

To be honest with you I do not know I have only had to treat a fish with internal parasites but the fins look like it might be in a more advanced state of brook

I do think the RO dips are helping but not certain if this alone can fully treat the condition and are probably just buying you some time

The red spaghetti worms in my sand bed is attacking the fish I thought they were supposed to be reef safe
