I bought a pair of "Julies" from a local breeder (F1's) about 2 months ago. One is signficantly larger than the other and I was told that this was the female. They got on fine for a long time, however within the last 2 weeks there has been a major falling out. The male now hides at all times with the exception of feeding time when he grabs a snack before being chased into hiding again.

I know that rock work changes can trigger this, but there haven't been any major changes. Does anybody have any suggestions to bring piece again? There are a number of juvenile Tropheus Duboisi in the tank (they don't get involved) and a trio of juvenile Peacocks and a pair of Daffodils.

Will I have to separate permanently? Would removing 1 temporarily and reintroducing work if so do I remove the male or female?

Hi mate

I don't have a solution but i do sympathise, i had exactly the same with a breeding pair, i fished out some fry and after the disturbance the female actually killed the male overnight.

I have also had situations before where i had a group of Julie's getting on fine, i moved the tank about, and after that all hell broke out!

However i've had some success too

recently i had a Marleri and a Dickfeldi who hated each other in a 300 litre, i moved them both to a different 300 litre at the same time, and for months after months they were breeding together in a malawi set-up! I had tons of fry growing successfully, amazing parental care.

good luck

Not had any luck with Julie's in my tank, always ended up with losing them, I'm sure they fought till the death as it happened a few times. Gave up on them in the end

I don't understand why but they are friends again. If you read my thread about tropheus bloat (Long term project at risk) you will know that alot of drugs and water changes have been going on and this involved slight re-arrangement of one of three rock piles. This was to ensure the heater stayed below the water line during the 80% water change. anyway following that the female stopped chasing the male so he is out and about with her again. Mystery.
