Angelfish bully?

HI all,
I have two angelfish that have been very happy for over 3 months, now all of a sudden one is bullying the other all the time. Any idea's

 

Welcome to the forum

If you could fill out your aquarium information, or even provide more information about your tank such as size, filtration, stock, it would give us something to go on to figure out why your angels aren't getting along.

 

Hi,
Trigon 190 tank
angelfish x 2
guramis x 6
platties x 6
plec's x 2
mollies x 4
real plants x 4
silk plants x 2

hope this helps.x

 

6 gouramis? What kind?

 

2 x honey, 2 x pearl, 2 x dwarf

 

Well, as fish grow and mature, the dynamics in the tank can change. Besides, 3 months is not long enough to claim that it ever really worked in the first place. I think the tank is small to house the angels with all those gouramis and others.

 

maybe slightly over stocked, but apart from the angles all seem very content.

 

Well, 190 liters is about 50 gallons. This tank is far too crowded IMO. Overcrowding always leads to heightened aggression and disease from the added stress.

What are tour parameters?

Your angels seemed content ("very happy") until recently.......

 

did u get them young? they most likely have hit fish sexual maturity or have set up territory (kinda long for this but could be possible). the tank is small which also causes issues with aggression. Normally id suggest adding a few more to spread aggression out, I.E having 5 fish of the same kind in 1 tank means one will not get picked on as much, but your tank is a bit to small to try this, you could try and do more water changes I have a super over stocked 100G but everything stays under control and the fish are happy with enough room to swim etc but you have to be willing to keep the WCs up, If I don't change the water at least 1 once a week level get toxic, I found this out the hard way.

The other option, the more easy one is to sell one angle or donate it to your LFS and just keep one, or upgrade the tank? Honestly I would wait a little while see how it plays out they are cichlids they will fight, my misses is always going off tapping the glass and all but its just there nature angles won't fight as much but it will happen even discus fight from time to time as long as the other one dose not get over stressed or beaten up bad it should be fine, just add some hiding places and keep and close eye on them.
