Are you sure your female Dovii has HITH. Can the holes be scars from physical injury or bacterial infection. HITH is normally associated with soft water fish. Dovii is hard water fish from CA and is not known to be susceptible to HITH.
Treating the tank is a last minute resort that is not really effective. The best treatment is ingestion. You can get metro over the counter (hikari/seachem) or measured dosage from a vet which you can then soak food in for ingestion. NLS also makes a pellet called HEX that is suppose to be very effective which mixes metro and epsom salt. There is also just treating via epsom salt soaked food.
If you go to the disease section you will see stickies on this and tons of posts. Hith is the likely cause of death of my fish where I treated multiple times over 2 years. If you can get to them to eat, that is the best. Next step is figuring out dosage.
If your fish eat pellets, personally I would get hold of some NLS Hex-Shield. Hands down one of the best options currently available. If that doesn't clean your fish out, they don't have HITH, or are too far gone to be helped. If they flat out refuse to eat the food then you need to become more creative.
FYI ..... both Epsom infused food, and metro infused foods has been used. The problem being that according to experts such as Noga et al, when feeding metro it requires being dosed at a certain rate in relation to the weight of the fish. Not always easy to do. Overdosing can create secondary problems, such as organ damage. The main issue with gel food is that some nutrients (such as vitamin c) and the medication itself (Metro), will be negatively affected by the temp of the boiling water.
Definitely not physical injury. I have had an umbee with HITH before. It sure looks like it to me. Small pitting all over her face and definitely some lateral line erosionAre you sure your female Dovii has HITH. Can the holes be scars from physical injury or bacterial infection.

How would I calculate the metro dosage of the food is just going to be soaked in it. Also is this metro the metro+ from hikari or something differentFrom an old post of mine .......
Almost all fish medications have the potential to be dangerous and/or toxic at high enough dosage rates, or if used excessively. It's been stated by at least one researcher that excessive use of metronidazole can cause organ damage in fish.
In fish, an excessive use of metronidazole can damage kidneys and other internal organs.(Bassleer, 1983)
Also, Metro applied via feed should only be done based on the fishes weight.
Dr. Edward J Noga suggests:
1. Bath
a. Add 19mg/gallon and treat for 3 hours. Repeat every other day for 3 treatments.
2. Prolonged Immersion
a. Add 25mg/gallon and treat once daily for a total of 3 times.
b. Add 95mg/gallon and treat every other day for three days.
3. via feed
25 mg/Kg of body weight/day for 5 to 10 days, or 100 mg/kg of body weight for 3 days. Retreat once if required.

If I'm soaking the pellets in the metro what would be the point of weighing him? The pellet is going to soak up the same amount of metro either way. I'm just wondering how long to soak and how many pellets to useMetro+ is b hikari and seachem has a product. If the fish is relatively healthy I'd say catch him and weigh him. I did not do this because my rhom was 17 years old and I thought it was too much stress.
