Oh dear...I thought I had researched, but it's clear there are huge variables within the species.
I guess there's always rehoming if things get too feral with the dragon blood. My OB is really timid thankfully.
Its something I've realised since trying to learn this side of the hobby. With Africans a lot of species just get stuck into certain groups, compared to other areas of the hobby where very specific nuances are identified between different species e.g water hardness, diets, sizes, behaviour where as with Malawi its often grouped into 'ok' and 'not ok'.
When I've looked at Mbuna and started to learn about species like Acei and Labs, they are so different from the other families of Mbuna its quite interesting to learn about and I can take that knowledge for my tank and know that having an Acei species as a 4th group in my tank increases my chances of success because they wont compete for the rock work as much as the others, in the wild they live in the top meter of the lake and behave almost like a schooling fish. But sometimes the level of research is simply Peacocks or Mbuna and then have at it but I think there is real value in researching the specific species before you buy them and go to a store knowing that you want X and also knowing why you want X - eg its probably got the right temperament for the other fish, the right colours (for aesthetics but also to avoid aggression), right diet etc - or like I mentioned above where Acei will be less competitive for rock work, in a Peacock tank Yellow Labs are an interesting option as you can keep a group with Peacocks, the hybrid risk is low (though still possible) with Peacocks and they will live between some rocks and the open water - meaning you have a balance of aggression because you have a good number of fish in the tank to spread aggression out but also a group of bright yellow fish that won't be taking up space in the open water all the time if that makes sense?
There is probably a fair to good chance that a lot of the time when people just chuck in mixes of Malawi together they survive because they can be so unpredictable but I don't think they will thrive, but a lot of Malawi tanks are judged just on survival. But, then I also think even if you did everything to the letter there is still a risk of failure as these fish are so unpredictable which is why (for lack of a better phrase) I think the standards are lower on the Malawi side of things. By standards I mean, its common keepers don't know species names, its common risks are taken, its common aesthetics come before welfare, its common unusual tank mates are put with them (e.g Clown Loaches or L number Plecos) - I'm not saying you are doing this but its just part of Malawi side of things and its easy to compare your standards against others doing this and thinking well I'm not doing 'that' so 'this' must be ok. But I'd argue if you come home and have to ask what species you've bought you've not done enough research.
As I've started my journey to the Rift Lakes side of things I've tried to take the same kind of approach that I do with anything else which is research to the point I can walk into a shop and know exactly what I'm looking at before I buy anything. I've done this the other way many many times with many many different types of fish and its gone wrong many many times, similar to here but in the past it was with Americans for me.
Anyway enough of my inane ramblings
