The NaCl won't be a problem as the sodium salts of phosphoric acid are easily water soluble, the same is true for any other acid you may add. You shouldn't get any form of precipitation when you add acid to your water to lower pH.
The only thing that will happen, apart from the pH dropping, is...
Welcome to the forum. Just add a location to your profile and I am sure someone will be able to provide some information about sources for apistos in your area
As Paul said, it can take from a few weeks to a couple of months depending on the type of leave.
If the leaves are dried dead leaves you won't have to worry about nutrient/ammonia spike as there is not much left in the leaves in terms of nutrients.
I have put up to maybe 3-4 good handfuls of...
I can't speculate on how often apistos spawn in nature, I just don't know enough about them in their natural habitat.
In my tanks they spawn mostly readily during the (southern) summer months when the water is warmer and slow down when the temperatures drop to minimum temperature set on the...
If you go into the literature you will find that the locations where A. cacatuoides has been found are closer to the Andes and in areas where there are more minerals in the water with usually 5-12 dGH, 4-16 dKH, up to 510uS conductivity and pH 6.5-8 (Staeck and Linke).
A. cacatuoides is rarely...
Many types of leaves, once brown and dry, are suitable. Most commonly used are probably oak, maple, or Indian almond leaves, depending on where in the world you are or what you can your hands on.
The important thing is not to pick green leaves but use the leaves that have naturally browned and...
If you go to fishbase.org there is an option to search by ecosystem. The entries for the Rio Negro basin include the tributaries, I think. There are about 350 species of fish listed for that ecosystem, so you do have some choices :)
I don't have sp Wangenflecken, but in most apistos I have the mother will try to drive the old fry away when the new spawn arrives. In a tank where room to escape is limited she may end up killing quite a few of the older generation.
But then, I had some pairs where the mother only gave chase...
That is not unusual amongst apistos. If the female is not willing to breed the male will usually try to chase her out of his territory, hoping a more willing female comes along - little does he know...
Once the female has laid eggs it is usually the male who has to be cautious not to get too close
I'd say two males as well. Several indicators: the strong coloration of the fins (although that can be misleading in some line red strains), no leading black edge on the dorsal, what looks like the beginning of extensions on the dorsal, and a poiny rather than rounded back end of the dorsal...
You can add a few pieces of floating pipe as additional safe spots for the first couple of weeks until things settle down.
What they can't see they don't chase or try to kill...
100L is maybe on the small side for a pair each. The two species are different enough that they may tolerate each other but the males may still try to claim the whole tank for themselves. Once a female has eggs or fry you will have additional aggression.
To make it work you will have to have...
As a very broad book covering cichlids in general, including the African cichlids, I quite like the book 'The Cichlid Aquarium' by P.V. Loiselle (published by Tetra, the edition I have is from 1994).
It contains a lot of excellent general information that help to keep various cichlids under...
He'll be fine by himself. As long as the water quality is good he should live a long and fairly happy life: no predators, food every day...
If you add a female your community tank may become far less harmonious should she decide to lay eggs.
Difficult to say from a brief description like that. But your ammonia should read zero, so it could be an infection due to environmental stress.
Best course of action in most cases of illness is to start with a couple of water changes to make sure water conditions are good. Often improved...
I have seen this with the borellii I keep. The two females in the tank always seem to synchronise their spawning and over time one female ends up with all the fry
