I have a pair of gold sevs who spawn but eggs are never viable.
They were small @first spawn, fresh from a lfs, so their age was questioned and whether they might've been stunted.
but they have grown steadily and resumed spawning at 6 inches or so, current size.
I have watched them spawn & verified a male and female. not 2 females.
Do gold sevs often have egg viability problems? I assume, being man made morph, they are almost as inbred as Super Reds.
I don't care much about fry, but it's a bit sad watching them dutifully guard repeated batches of dead eggs. they're trying new rocks & locations, etc now.
I have 2 younger males, sent as Super Reds but only one is becoming red spotted. don't know if the female would have any luck with one of them. seems like chances would be even slimmer with known Reds in genetic background.
 
any answers regarding if the male is probably shooting blanks, or whether female's eggs can just be bad?
I'm mulling over which of 4 sevs I will keep.
 
No experience with this but had tried to research this myself some time ago related to the super red / red spotted sev. From what I could tell there seems to be some consensus that a high percentage of gold sev males shoot blanks. I also found some reference to there being a trick that can be employed that is used for other fish like angels to help keep the eggs from fungus better. I never found a good description of the technique or additive. It wasn't simple methyl blue - it sounded like something more/different. Seems like the guys who know keep pretty tight lipped about it. If you haven't been successful with your current male I would try one of your others. I got some super reds that I bought small and came looking like regular golds. I thought I got ripped off but I ended up switching a bunch of things and they colored up. First thing is they put on some size - that might have been the needed thing - they were +3" with little color though - they are around 4" now. Second thing was I gave them some more space and removed the more aggressive tank mates (red parrots). Last thing was I changed food from an attempted NLS knockoff to straight NLS. Not sure which or if all of these things did the trick but they are gorgeous now with red covering most of their body.

Good luck and keep us posted on any progress!

Patrick
