community tank babies???

[Magnum Man]

as the bulk of my previous experience was with cichlids, when I reset up my tanks again, about 3 years ago, I wanted community tanks, that the fish wouldn't breed in, and destroy the dynamic I set up ( past cichlid experience talking )

have you ever had a fish that bred in a community tank, and the eggs / fry survived, at least a few???

I guess I have a few tanks, that I'm surprised I haven't seen babies yet... specifically the king tiger plecos, or panda garras, or one of the South American tetras, but expect the crowded tanks are too much pressure...

I do have 4 tanks of breeding neo shrimp, that most have live bearers breeding in them as well... I did put mountain minnows in one, but have come to really like those, and may move them to a tank where they would be more visible, and replace them in the shrimp tank, with another small live bearer, as the other tanks have been working out...

I had one male cherry barb (Puntius titteya unless its name has been changed) hatch and survive to adulthood in my community tank.
I used to have 3 males - 2 purchased males plus the one which hatched in my tank. I now have one. I found the other two dead on the same day at the end of last year, and I have no idea if the single male I now have is one of those I bought or the one which hatched.

In a tank with guppies, Platy, Mollys and endlers all four species have given birth with the survival of fry to adulthood. In a tank with Kribensis, yellow tale Congo tetras, julies and butterfly cichlids, both cichlid species have produced fry that have survived. It is the third spawn for the butterflies.

Yes. Often. Livebearers most frequently but also Nannostomus, Pethia (barbs), Danios, "Corydoras" etc. In my 75, which has been set up for decades, there is a school of Hoplisoma metae whose ancestors go back to when I initially set up the tank. They spawn all the time and a few fry usually survive the gauntlet. Enough to sustain the colony.

In a tank that has been running unchanged for about 6 years, featuring originally 10 Colombian tetras, 4 clown loaches, and 4 Corys (leopardus), some reproduction has occurred.
The adult Colombian tetras are older adults, close to the end of their lives, and there are only 5 left, but since the beginning of this year, several successful spawning have taken place, resulting in 5 juvenile tetras, now approaching 1 inch. There were more young ones, but just 5 made it long term. Also, there were several batches, judging from the size range of the young ones.
What surprises me is that these babies survived despite the clown loaches, which are notorious for eating any eggs from egg scattering fish. I guess being a heavily planted tank helped.
Other than that, guppy’s, tuxedo platies, and Cories have bred in my communities (other tanks) despite my doing anything to protect spawns or stimulating them. Cheers.
