At my wits end with aggression...

  • We are currently upgrading MFK. thanks! -neo
Also I find to much rock can cause more regression (I now contradictory compared to what you are use to herringg)
I find open swimming area to be helpful , Im not saying remove all rocks but I believe there is a balance
 
Agreed . I find when adding females to my tank itv will raise the aggression of the males , Try a all male tank .

It is an all male tank. There was fry a while back, but pretty sure I got the female out.
I don't think the BB made it... it was head down last night barely moving, and I couldn't see movement before work today (he was hiding in rocks) so need to check him tonight and see what's what.
Most of my rock work is on the right side of the tank, leaving the left side mostly open, so they have caves and free space.

Edit: it's just irritating because until the last month or so, I hadn't had any serious aggression issues (causing injury) just a couple fish that got skittish and usually came out of it as the aggression shifted. The tank has been running almost a year, and the majority of the fish have been in there the whole time.
Guess they're growing up and flexing their muscles.

I never had any luck keeping mbuna with haps and peacocks even in my all male 220G. I had a fully grown red zebra, hybrid yellow lab, and kenyi. Eventually had to get rid of them because they were always fighting amonst themselves and fighting with my haps and peacocks. The tank is calm now with only haps and peacocks ranging from 4"-12".
 
Just saying this is why I left Mbuna. Too frustrating for such a relaxing hobby.
 
How awesome it is when its peaceful makes up for the aggression for me. I've accepted my red wolf will sometimes snap and kill things. Its happened a few times now, just need to separate him. I don't mind the chasing of cichlids, it seems playful to me. My stalsbergi and festae chase a lot but rarely nip, if anything my teugelsi will sometimes join the fray and nip. Which I find odd for a small bichir. My other teug from the same batch is normal

Well the bumblebee didn't make it and I found a place for the albino, and the tank seems to have calmed down quite a bit. I had a couple of fish getting skittish (mainly my dragons blood peacock) and they've colored up and come back out of hiding...
Now if only my firemouth would heal up and come out of hiding in his hospital tank...

Separate the Mbuna, SA cichlids and Haps/peacocks into separate tanks. The 3 types of cichlids are not compatible (especially mbuna) with one and other, always inevitably ends the same way.
 
I think you should try adding more fish to your aquarium! I had slightly less than that amount of fish in my 40 breeder.. You aggression is likely territorial seeing as you have multiple victims and bullies. By adding more fish you eliminate them becoming territorial and singling out one fish! The bullies will have multiple fish to fend off and victims can escape getting intertwined with other fish.. just like hiding yourself in a large crowd. I had a friend with a 90 gallon who had 40+ fish and ZERO problems.. mind you he was extremely anal about taking care of them.
