How to indroduce new fish to established cichlid tank?

[AnomalocarisAquatics]

Everything Central American can breed together, for the most part.

Even GTs?

Even GTs?

GT or Green Terror (Andinoacara Rivilatus) is a South American fish, from West of the Andes mts in Peru, Columbia etc.
It can breed with other Rivilatus and reports of successful crosses with Andinoacara Pulcher, a cousin



The only know South American fish that can cross with Centrals is the Mesoheros Festae or Red terror, also from West of the Andes mts.

The Andes mts is like a genetic barrier. All things east of them like a certain water, West is a different water. East typically can only breed with itself, West is more open with the red terror being able to cross, says they are close enough related still, vs cichlids from the east.

Don't you think if they could cross you would see all kinds of crazy crosses all over YouTube?

Mom's an angel fish
Dad's a red devil

The only cross videos or Hybrids are of Centrals cause they are the only ones that can

I would consider adding hiding spots that aren’t accessible by the jag. Then your other fish will have a place to retreat to if bullying starts

All Cichlids can be Taxonomically broken down into Tribes, and here may be the reason some breed regularly across continental divides, and some don't.
The genus Parachromis (where jags are found) is from the tribe Therapsini
The Andinoacara (where GTs are found) is from the tribe Cichlasomatini,
The tribal separation of these clades (tribes) may be a key (or not) to inbreeding
However divided geographically
I have heard about cross breeding between the Uruguayan and Argentine genus Australoheros (tribe Therapsini) with the Central American genus Amatitlania (also Therapsini)
Just as may be the case with Mesoheros festae (also from the tribe) Therapsini.

And although I mention it, I find creating hybrid mutts abhorrent to future cichlid diversity, leading eventually to the creation of future generic sameness.

Maybe obvious but needs to be stated: Make sure to quarantine whatever new fish that you add. Dumping in a new fish without quarantine, in addition to exposing the existing fish to disease, puts the new fish at further disadvantage and stress.

Also, better to add several new fish vs. just one. Site breaks and rearranging the tank before adding new ones is good.

Also, there have been a few records of amatitlania breeding with andinoacara, so the distance from therapsini to cichlasomatini might not be safe even... Theoretically by that logic you can breed convicts with discus, as they are also in therapsini.
