Aggression out of control....
« on: January 13, 2018, 12:15:53 AM »
I now have 8 mature Peacocks in my 75G and the aggression is crazy.  One tank boss that has the rest cowering in corners almost all day long. Then, the number two will start in on the others. I lowered the tank temp to 75 to see if that helps, but it's the same. Rock work hiding places has not worked.  None have been killed as of yet but there are plenty of torn fins. Do I add another 5-6 fish to overstock, or just live with this.......can't believe I'm saying this but I'm tempted to dump these fish and start with something else.....

I doubt that adding extra fish will stop the tank boss from being and a**hole, he will just have more targets. I have been lucky in never having any real issues with an overly aggressive fish (except for an OB peacock that got moved on). Always had my C borleyi as a tank boss. Bigger than the rest, but not aggressive.
Do you have a spare tank that you can move #1 and 2 into for a while? Give the rest of the fish a chance to recover. Then try and put them back in after a few weeks/month and see how it goes. May go back to the way it was and you may have to move those two on. Iíve had to move plenty on over time until I got a tank that is balanced.
Life is all about options, as long as you have something to look forward to, there is no reason to look back...now where can I put the next tank?

I've moved a good number of fish as well, but each time another fish takes control....I've also isolated aggressive fish in a fry net, but once released they start in again. I do have a 10G that I can use with a separator to keep the two trouble makers apart. I might try that, or switch to guppies  :D

I might just be lucky, but I also have 11 males (and 5 female/juvie borleyi) in a 180 gallon. Plenty of room for all so they are not fighting for space. I do want to add 3-4 extra males but am a little worried about upsetting the balance.
You could fit a lot of guppies in a 75 [emoji6]

I have had that issue only once when I was keeping all males. I put the over agressive in a timeout for a few days and it happened to work out for me. Seems you have done all you can and last case scenario is to just move the fish on. Sucks when that happens but sometimes things just donít workout. Consider yourself lucky this is only the first time your dealing with this.

I have already moved 3 or 4 fish because of aggression. This is my prize otter point, the fish in my avatar, so it will kill me to move him on. I'll try isolating him first.

It's never fun moving fish on but it's always for the benefit of the tank. Especially when it is one of your top fish. How about a setup for him with some females? Breed a bit :02

sorry to hear john. things were going well. sadly its just the nature of these tanks. thats why i switched. i was so stressed out trying to keep things going. to answer your question, im not an advocate for over stocking, im not sure why that has become gospel in the community. adding more fish will likely throw the balance off even further. i honestly think my problem was my tank was too small for adult peas and haps. hopefully you can reign them in.

Yea it always seem to be one of your favorite fish!! Mine was my protomelas splitonotus tanzania which fortunately worked out for me. Try isolating him in the main tank so the other fish can see him. I used a little plastic hermit crab cage and put him in the main tank. Good luck john

OK...the terrorizer is in solitary, and small fry net inside the main tank. Figure I'll leave him in there for about 4 weeks and then put him back in the main. If that doesn't work, to the LFS he goes.

Moving him on is the best way forward. I have moved two fish on a  jewel cichlid that just chased all other fish all day 24 hours a day it seemed and a fusco that just attacked everything even my hand and the glass lol. my tank is now so much better aggression wise .  I am happy with it new they was great looking fish and it was hard to get rid of them but I had to. I found them good homes friends from my local fish club had them. Its all good I gave them free and I have had fish from others free also.

Fish clubs are a dying thing in most places in the UK how are they doing In America?
I feel lucky to have one so close that is still going with 243 members and apparently it only had 73 members 8 year ago.

I deal with aggression by moving fish on to my local LFS my mbuna can be total assholes once they reach adulthood. I have a few different tanks and have been quite successful at breeding the fish its kind of hard not to be if you have males and females together I literally have hundreds of fry right now. Red Zebra, Yellow Labs, Maingano, Albino Socolofi, greshakei and some greshakei hybrids that are crazy looking. I am considering moving most of the adults on and starting over with the younger fish they are much less aggressive and with mbuna they are just miniature versions of the adult with nice color. 

Part of me wants to just pick the least aggressive fish in my inventory probably my Maingano and Yellow Labs for my 55 gallon and just stick with that they don't get too big and they are my easiest to sell to the LFS. I also am flirting with the idea of switching my 40 gallon breeder over to a Tang tank with some calvus and julies I know they are a lil slower moving but as far as less aggressive I don't know.
75 gal    1 M 3 F Metriaclima greshakei (Ice Blue Red Top)
             2 M 5 F Labidochromis caeruleus (Electric Yellow Lab) 40 fry in grow out tank
             1 M 1 F Metriaclima esthrae OB
             1 M 3 F Pseudotropheus cyaneorhabdos (Maingano)
40 gal    1 M 4 F Metriaclima emiltos Mphanga (60 fry in grow out tank)
             1 M 1 F Metriaclima elongatus chailosi
40 gal    1 M 3 F Cynotilapia zebroides Hara White Top Gallireya Reef (over 100 fry in grow out tanks)
             1 M 3 F Chindongo saulosi           1 M 3 F Metriaclima callainos (Pearl Zebra)

I brought them to a place I haven't been to before, about 35 minutes away. Its an established store that has just changed hands. I spoke to one of the  new owners for a while, who was a nice guy. They have plenty of tropicals, some marine fish and corals, but a limited number of cichlids.  The place is pretty run down, but they have plans for upgrades as they go. I hope they make it because there are very few decent privately owned shops around any more.  I ended up with a container of NLS pellets in return, which is more than I expected.  I guess it's time to change my avatar !!
