At what size or age does a Flowerhorn gets aggressive ?

[chopsteeks]

Currently have a 2" Flowerhorn in a community tank. So far he/she is getting along with other fish. But I am aware that I need to move him/her on a tank by himself/herself. When does a Flowerhorn gets territorial ?

Also how fast does a Flowerhorn grow ?

Thanks.

It really depends on your flowerhorn's personality but if so far he got along with other fishes then it should be okay. My flowerhorn does not want to be near anyone when he was little around 2 inches. They do get their sizes pretty quickly like 5-7 inches depends on your feeding in a year of age or so.
