My Livebearer Tank!

[heygetsmart]

I started a live bearer tank about 3 months ago. I started out with
3 sunset platys
3 red wag platys
11 female guppies
3 male guppies
3 silver mollies
3 dalmation molies
6 ballon mollies
3 swordtails

3 months later.. all the original parents are still alive, with give or take a couple hundred of babies!

Tell me what you think. The tank below is a 35 Gal, I believe.

And here is the upgraded tank, it's a 44 gallon.

I think buying more tanks to house all of the production from healthy livebearers is a futile effort. They can easily add to the population faster than you can afford to buy new tanks. You can take it from me, with 25 tanks up and running, there is no way to get ahead of them. The easy egg layers are even worse with hundreds of fry from each breeding instead of just 40 or 50. Instead of trying to keep up with the breeding, stop trying to save every fry. Enough will survive that you will have plenty to give away and the predation will limit the population to one that you can sustain. When you want a new tank and have a purpose for it, go ahead and get one but don't do that just because you feel all fry must be saved. On average, in the wild, one fry survives to replace each parent and that is it. Otherwise the world's creeks, streams and rivers would quickly become a solid mass of wriggling fish.

Hence why I don't save any of them [ : I had a couple of breeders in there to let the pregnant females drop.. but eventually my females all got pregnant at the same time. I'm thinking about adding an angel in there to keep numbers down. And I use some of them as feeders for my bullfrog/koi. I would only want the strongest to survive anyways! Darwinism at it's best!
