Sorry you lost your female Red Headed Tapajos. 
You may need to try a different strategy in keeping those Earth Eaters in the aquarium.

So, yeah.....

-Be careful with that one. And yes, I do like the thought of breeding out the Red Headed Tapajos Earth Eater. But, what gives me pause on this, is that this species doesn't 'Pair Up' or form spawning pair bonds. In the wild, the males typically hold or keep as large a harem of females as their dominance and aggression will permit. This makes for pretty dominant/aggressive males of this species in the aquarium.
Wife beater?
So, I usually recommend keeping these in 1M/4-5F groups. Seems to keep the females somewhat safe that way, when the spawning aggression from the male is spread out over larger numbers like that. In the aquarium, when the female releases the fry it's a bit like an African Mbuna situation. I used to keep my holding females (WC Geophagus crassilabris) in a separate/quarantine tank (55 gallon tank) until they spit the babies out. The babies were safe to raise out by themselves that way. And most importantly I didn't have to compete against predation from the adults in netting up those baby Earth Eaters to raise out. Plus, I suspect the 'Mom Fish' sort of enjoyed the break as well from the rough and tumble of the 180 gallon community tank. That ridiculously aggressive male G.crassilabris sometimes left his females looking like a lawnmower ran over 'em or something....
So, yeah.....
