Aaaww! The pics are blurry, sure, but they look like the black mollies that have bred in my dad's tank for the last decade or so.
Long story short, I took over maintaining his 57 gallon tank a year or more ago, since mainenance is too much for him now he's in his 80s. He's also decided he wants me to take the tank, so he can use that space for some of his birds and close down his outdoor aviaries.
But for the last 8-10 years, they've had these large black, silver and blue mollies breeding in there;

That's one of the original trio that were absolutely ancient, and huge.
For scale, that's a 57 gallon tank, and they were enormous.

Every now and then, I'd bag up a bunch of the youngsters from these and the other fish, and take them to the store. They produced some really nice babies, ranging from a pure jet black, to mostly silver and blue with some black speckling. Since I knew they'd had the original trio for way more than five years, I'd held back a trio of the nicer youngsters, and there were some other black molly babies in there that were still too small to go to the store.
Over the last few months, we gradually lost the original large trio form old age. Sad, but I knew I wanted to keep the young trio to keep the line going when I took the tank, my mom loved these fish, so I wanted to keep the line for sentimental reasons.
Then, my dad decided to unplug the filter without telling me! Mid-Feb. One day, fish started dying in big numbers, I had no idea why, until he finally told me he'd unplugged the filter... Lost so many fish, including most of the remaining black mollies
It had been overstocked, and I'd been slacking on maintaining the tank a bit in the previous months, but the wipeout was still worse than I'd have expected, since I was straight on to water changes and fixing the filtration. I don't know whether it was a bad enough spike that it killed a lot in one fell swoop, and damaged a lot more who just went belly up in the weeks after, or if they were weakened by the spike and then some other kind of infection took over or what, but ended up losing most of the fish in that tank.
I now have one young black molly left. That's it. I'm hoping she's old enough to be carrying sperm packets and can get that line going again. I will get a new male when I can for new blood anyway, but still. I'm glad I moved that female to one of my tanks when the losses hit.
Anyway, sorry for the essay ranting and whining! Just that your fish remind me of these guys, and I'm still super sad about losing those. The young trio I'd saved were beautiful, and the male had been determined to knock up the girls, so I'm gutted they're all gone. The female I have now is a plain black one, but she'll be carrying those silver/blue genes for sure.
