From a couple of other sites;
eSha 2000
6.3 mg ethacridine lactate (Rivanol)
1 mg proflavin
3.2 mg copper 2+
0.26 mg methyl orange
1) Ethacridine lactate, marked in the 1920s as Rivanol, is an
antibacterial acridine. It is sometimes used to treat shigella.
2) Proflavin is another acridine that is very closely related to
acriflavin. It's good for killing protozoans like velvet, gram positive
bacteria, and fungus.
3) Copper is also good for killing protozoans like ich and velvet.
Works best but is most toxic to fish in soft water.
4) Methyl orange, good for??? It's normally used as a pH indicator in
aquarium alkalinity test kits. I've never seen it mentioned as a fish
medicine.
This is an antibiotic-free "scattershot" medicine, and it is reasonable
to try it for anything in the leaflet. It will have the strongest
action against protozoans like velvet, tetrahymena, and possibly ich. I
assume by blocking NTD they mean that it kills free-swimming parasites.
This does sound like a decent broad spectrum med, I was going to suggest copper sulfate. Acriflavin is one of the things I use in hatching tanks, it sounds like ESHA 2000 has something similar.
What I usually do with fry once they are swimming is med with copper sulfate at half the dosage for the first week, as long as they are in a separate tank. Copper is a broad spectrum medication, knocks back a slew of things giving the natural immunity of fry a chance to build up a bit.
I do not advocate medicating well fish, but there are certain things you have to do to help out mother nature when breeding. Many of the fish I breed originate from softer more acidic water. Acidic water has a bit of anti-bacterial/fungal properties to it. I have harder more alkaline water, so I do have to do a bit of chemistry to make things work.
As Wilder stated, you have done all you can, breeding is a learning experience, at times that learning curve can be steep. Don't be discouraged, it can take a few tries to get a batch of fry to grow out without any problems.
