I have only 20% expireance or direct knowledge of the '5 Rivs'. However the
referance to the Zifideous I can respond to.
That is one of the things that makes a killie a Hard Fish. Those fish only lay
one maybe two eggs a day. Total of 10 or so eggs a week.
That is a slim start to figure out how to raise them. Even when you get them
to breed to maximum potential it is a critical struggle to raise the fry.
Add in to that the fact the fish need almost a full year to reach maturity
there are just so many steps on the path that are critical where you can lose
the lot of em.
They are gorgous beasts and worth the effort but the element of a total crash
of the effort is present every day.
I had the Zifs going and loved every day of the project. I had a population
that was throwing a GOLD morph. I put so much effort into keeping them around
in hopes of isolating that morp. But 9 months of intensive care to raise a fry
to producing parent was beyound my concentration. .... I got the obscurus ...
I love every day of the challange. They have been here a year now... ( Thanks
for smuggeling them into the states Geert! ) ... still alive and breeding , I
have however just not gottin into establishing a regimine to implement the fry
production end of it.
However I have had R. derhami and R. magdeleni that are as beautiful and
dearly luved as well. The exception is that when these guys are in breeding
condition you get a 100 eggs a week and can have error in the fry raising
routine that will not totally wipe out the species in your collection. It is
nearer impossible to wipe out all the fish when you have that number of them
hatching each week :)
With the more prolific species you can actually do a poor job of raising fry
and still have fish to share with your friends.

proverbial p.s. - I had some wild population of the geayi! They did very well
in a natural setup of how I keep my tanks. Ask if you want details on that
one. I would rate them as fairly prolific. More productive than diapterons,
Not as productive as annulatus. They were not that beautiful and so easy I
lost them through disinterest. Kinda the day all the water evaporated I
realized there were no more fish swimming around the tank, eh? Yep, I
dehydrated the wild fish, and a bunch of F1 fish, fry and eggs. oh well, such
p.s.s. - best start is find the biotrope specs for the native waters and start
there. That and a lot of TLC should get you to the starting point of the pairs
p.s.s.s. Guess what I am trying to expound is that the difficulty attributed
to maintaing a kille may well have more to do with raising the fry than
getting the pairs to produce offsrping and the quantity of fry they yield for
you to learn about them.
