I strongly agree with Harry in regards to the mortality of the parents,
and the near invulnerability of the fry. I also found out why, when a
shipper started offering fresh-water guppies. I called him on it and
asked what the deal was. He explained that it is common practice in Asia
to breed Guppies in hot and very brackish water. They grow faster, and
there is less diseases which will tolerate those conditions.
The problem is when you now put them in your home aquarium, the parents
become sickly and do not live very long. They just live long enough to
drop a few batches of fry, and get past the LFS warranty. A teaspoon or
tablespoon of aquarium salt per 5g won't be enough to make much of a
difference. For the modest price difference, I only order freshwater
Guppies now, and I've seen significant improvement in health and life
expectancy, but I'm at the mercy of all the players in my supply chain
being honest, as I'd never really know if they had been brackish Guppies
I haven't read the krib FAQ. Guppy fry would probably not fare well with
Rainbowfish (even dwarfs), but if the tank is large enough, some always
survive. If your water has some hardness, this will help a lot.
Whatever Guppies you get, it might be worth setting up a separate tank
and putting them in a breeding box to collect enough fry. This gets your
stock levels up enough so if/when the parents die, you will have a
As for an uncontrolled population, you can regulate the cull rate by the
amount of cover and the amount of food being given. In a 75g, I'd get
the stock levels up to 20-30 before worrying too much. jmo, ymmv
