Agression

Recommended Posts

this is MAtt again! I have posted several pictures of my 55 gallon tank in the album thing. i am haveing some trouble with agression and would like to know if i should either add 2 or 3 more fish to the 14 already in there? or if i should change the rocks so that there are only 4 or 5 large boulders and not many caves? thanks for ur help ahead of time... as always

Hey there Matt...how many fish of each species do you have?? that will make it way easier. Sometimes it is as simple as re-arranging your rocks. Or adding a couple smaller ones to form caves between the bigger rocks. If you have more than one male of each species that will also cause some aggression. Take them back and get females. If I can look at your list maybe we can figure something out.

the list is:

2 pseudotrophes zebras (male and female)

1 pseudotropheus flavus (male no agression at all)

2 yellow labs (male and female)

2 pseudotropheus elongatus (male female)

2 christmas fulu (male female)

1 Placidochromis electra (male)

 

(these fish are in 55 gallon tank with pictures posted in member gallery under matt's tanks) (o, and this tank has excenlant filtration: one emperor 400 and one fluval 303 so i could possibly add more fish)

 

that is a list of all the fish. it seams that the p. zebra female, x-mas fulu famale, and yellow labs are beet up. the p. zebra female is totally missing her fins and will probably die. :o i have recently changed the rocks around and have plenty of caves(look at pics and tell me what u think). i am wondering if i should either add more fish, or take all rocks out and have just 4 or 5 large boulders with no caves. thank you for your help.

I am suprised that the Xmas Fulu's aren't fairing well in your tank...Mine have stood up to everything.

 

2 pseudotrophes zebras (male and female)

1 pseudotropheus flavus (male no agression at all)

2 yellow labs (male and female)

2 pseudotropheus elongatus (male female)

2 christmas fulu (male female)

1 Placidochromis electra (male)

 

The first thing I would do is remove the Placidochromis Electra...they get way bigger than all your Mbuna and really don't belong in a 55 IMO.

 

Second thing I would do is make a giant purchase of sexed females (if you can). I think you are going to need 2 more Flavus, and at least one female of every other species. Maybe take your female Xmas Fulu out. 1 male will do just fine in a Mbuna tank (at least it did in mine).

 

Does your Elongatus look like your Flavus?? If so there could be competition for the female Elongatus causing some aggression.

 

Are those red zebras?? Maybe reomve them and replace them with Ps Acei maybe. That should look pretty good. Other then that, I don't know what to say. Keep the caves and hiding space, maybe add a few more? Its up to you.

 

Good luck

It seems like almost all your aggression is directly related to your sex ration. All mbuna should be kept 1m/2+ females or the lone female almost always ends up beat up. They are harem breeders even in the wild and in a tank, a female doesn't have much room to escape from the male.

 

I think taking some of the rocks out is completely going backwards. You want to add more rocks. Decreasing the amount of territory in the tank will intensify the fighting for the remaining space. Also, your females will have fewer places to hide from the males. The best thing to do would be to add more rock and arrange it so that the line of sight is broken up. Its "out of sight, out of mind" when it comes to fish aggression. In a bare tank, one fish will chase the other in laps around the tank. If that same fish darted around a corner, the aggresser almost always looses interest and stops the chase.

 

I agree about taking out the Placidochromis, they get a little too large for the tank and they really require a more protein rich diet than the others. Taking him out will free up a lot more space to add more females which your tank desperately needs.
