It may not straight away but sooner or later the jardini will hammer the knife's , the typical jardini will take over any tank although you do have a 450 with plenty of space my guess is it will happen eventually and usually ends in casualties and deaths
IDK about a Jardini I have a ~12" BGK with my Leichardti and they are fine together. Jars are more agressive and some species of knifs are also pretty agressive a clown knife and a jardini might end up woth one dead fish. Tank size also plays an important role the bigger the tank the better. My .02
I have a similar sized tank with a ~15" jardini and ~18" knife. Also a ~13" male red devil/midas (can't tell) and 4x ~12" blue gills my son caught in the bayou. The aro every once in a while gets into it with the knife, but for the most part they ignore each other. The aro spends most of its time attacking the RD/midas. When the cichlid ventures out of its territory, the aro quickly attacks and herds it back into its corner. SURPRISINGLY, it is the blue gills that are the boss of that tank. The most dominant blue gill chases the other blue gills around, easily bosses the much larger male cichlid, displaces the knife at will, and is the ONLY fish that can make the aro run away.
That's funny. That Jar won't run for long after it gets a few more inches on it, the whole dynamic of the tank will change.
+1 some jardini are late starters but most turn into Bronson before 15" , once its fully grown nothing will even test it hopefully by then it will learn to accept the tankmates that is if they dont give him to harder time between now and then , if they do keep on at him eventually it'll snap and smash something up in my experiences
The dynamic is definitely changing. The jardini was originally introduced at ~8" and avoided everyone. At ~12" it started to challenge the cichlid, at 13" it completely dominates the male Midevil. The knife was acquired about the same time at about the same size, but has outpaced the Jar in growth rate. The blue gills are the newest addition, added them about 6 months ago. Took them about a month to take over the tank. There's a pair of ~2' common plecos that ignores everything, including each other.
