Ryan good call on culling, although I know it was hard it was the right decision. Looking forward to reading on your summer project.

After two weeks of bickering and disagreements, the female is in spawning colors again tonight.
Third time's a charm?
Dang these guys are beautiful. Best of luck with the third time around Ryan.

I have free-swimmers as of Wednesday, July 29th. I lost a lot of eggs this time, and about 10 - 15 wrigglers a day for the five days they were wriggling, and even still I have way more fry this time than last time. I'm not sure what caused the losses, though.
This time around I sterilized the hatching tank and I did a formalin dip on the eggs for an hour before moving the flower pot they were laid on into the hatching tank. I've done a lot of reading about using formalin as a bath or dip for fish eggs to prevent fungus, but my main reason for the dip was to hopefully kill off any flukes or protozoa that might have been passed on from the parents. I'm thinking this is what caused the flashing/scratching issue with the last batch of fry. Unfortunately I didn't have time to clean up the parents before they spawned again.
The weird thing is that formalin is supposedly really good at preventing egg fungus, and yet I had way more eggs fungus this time than the first time. I did not expose the actual wrigglers to formalin -- I only did a dip on the eggs and then moved them into the sterile tank. So I'm still unsure as to why I had so many die-offs and so many fungused eggs. The free-swimmers that I have now are eating well and they have had two small water changes since Wednesday so fingers crossed that this batch goes better.
Hope this batch goes all the way for you Ryan.

Super nice!
It looks like your Heros are not the real Heros severum:
Abstract:
"Heros liberifer sp. n. is described from the drainage of the upper and middle Rio Orinoco in Venezuela. The new species is distinguished from all other Heros species by its unique colouration pattern of several horizontal series of tiny bright red dots on the lower half of the body sides and by its unusual brood care. Heros liberifer sp. n. can be distinguished from the syntopic Heros severus Heckel, 1840 by a distinct caudal spot, narrower lips, a bright red ins and the 4th vertical bar, which is not shortened, but extends from the anal fin base to the base of the dorsal fin. In addition, comments are made on the colouration of live specimens of Heros severus, its distribution and ecology"
Actually, this paper seems to be reclassifying the mouthbrooding severums into Heros liberifer. The full paper is not yet available, but Peter Dittrich wrote this on Facebook in regards to Heros liberifer:
That paves the way for another fish to be described as true Heros severus. It could be the ones I've got, or it could be something else. There are a few which meet the criteria of the half 7th bar.Itīs the new Name for the Mouthbrooder...The Mouthbrooder was named as Heros severus since 1994, But this was wrong. I know that Staeck & Schindler discibed this species at least on 6 samples from the Manapiare River (Laguna Piranha - a small Lake beside the Manapiare River). These Fishes were collected by my good Friend Roland Rietsch in 2012. Staeck get this fishes from me. Probably Steack & Schindler have used some fishes they collected by them self... But this is more than unlikely.
Ryan,
How is this latest batch doing?

Ryan, as the abstract says, the article will provide live photo and ecology of true H. severum, cant wait. It looks like the biodiversity of Heroinii subtribus (Mesonauta, Heros, Uaro, discus, angelfish) is much larger than we know at the moment.
Clarification from Juan Miguel Artigas Azas at Cichlid Room Companion:
So the mouthbrooder previously called H. severus (incorrectly) has been officially described as a new species, Heros liberifer.A new Heros species for what in recent years has been incorrectly known as Heros severus has been described by Wolfgang Staeck and Ingo Schindler in the journal “Bulletin of Fish Biology”. The new species Heros liberifer differs from all Heros species by a pattern of several horizontal series of bright red dots on the lower half of the body sides (versus no rows of red dots), tiny dark dots on operculum and cheeks in adult males (versus large dots or a vermicular pattern) and other aspects. It differs from its partly sympatric (having the same distribution) species H. severus in several morphological, behavioral and ecological aspects. The new species is a mouth-brooder, from which its specific name liberifer (Children carrier in Latin) was inspired, plus unlike H. severus it is found not only in black water but also in clear and white water, with a higher pH. H. liberifer is described from the Orinoco basin in Venezuela, but it can also be found in the Casiquiare River (that connects the upper Rio Negro and Orinoco basins) and in the middle and upper Rio Negro in Brazil.
