Hey spiff44, glad to hear the Pearsei are doing well! I think I spotted a glimpse of one in another post where you put up a pic.
I got into one of the best debates I have ever had about this topic nobody got heated and we had respect for eachother in the end but none the less people hold very tightly to their view point on this. The most common one I see is never mix new world and old world. I have also seen people get more specific never mix lakes, never mix SA and CA, right down to never mix collection points.
My view on it is don't say never or always. It is to general and to many variables. Just make sure the fish match temperate, size, and at least overlap in water perimeters but I believe the last is the least important unless wild caught because if you are buying in a LFS chances are they have never seen the water perimeters from there native environment.
My own expierence I keep a yellow lab with my Firemouth and Honduran red points and he just keeps to him self. I just added some Juvie Green Terrors to grow out that are the same size as him and he took after the GT's at first but he is fine with them now. It has been about 2 weeks since adding the GT but about 6 months with all the other fish together.
My understanding is that they take about three years to reach sexual maturity, so you have a little ways to go yet. Pearsei are very curious fish that seem to watch what you do. I think that is what makes them interesting. My girl shares her tank with a red bay snook, a regani and heterospilus and they all do fairly well together. Ever consider just adding a couple other Central American cichlids? (NOT a snook however, they have huge mouths and would make a snack of your little fish)The growth rate on these guys is insane… they’re now definitely the biggest fish in the tank and its kind of scary knowing that they’re still infants. But its cool too… I’m starting to see the attraction of big fish, these guys always seem to be slow motion compared to everything else.
They do seem to have more personality too.. at least they are very curious.
Agree with this! I think unless the fish are wild caught or you have extreme water, the varied water requirements aren't that big of a deal. When I kept Africans I kept them in my tap water, which is the same way I keep my SA/CA cichlids. I never mess with water, because I'd rather it be stable. Temperament is the big thing - most Rift lake cichlids would beat up SA fish. But that being said I also have a Yellow Lab in a grow out tank with SA/ CA cichlids and NA sunfish. So far so good.
This is why I'm sticking with herbivores. The two I have now are no more ornery than the few kissing gourami that I have. they ignore everything in the tank and only mildly annoy each other. The others I'm considering should be similar.. I hope.in my opinion most cichlid mixing in general is a poor life choice, Cichlids in general seem to be a poor life choice. I've never had a peaceful/community variant other than rams that weren't absolute pricks and that includes apistogramma and geophagus. Total jerks.
