Just moved and rebuilding my fish room and had a 10 inch L600 in with a jardini. The L600 is beating on the jardini. I hadn't seen this behavior before. I have seen pseudos chase all other fish away from a food source but he appears to be on a mission to get the jardini. Going to separate them before the jardini gets hurt, lol. I have seen pseudos actively seek other pseudos out but rarely other fish.

Separately, I had an L234 that appeared to actively go after other fish and bought himself isolation in the past. Anyone else seen similar behavior in pseudos or other larger more aggressive Pleco species?
 
If you had just moved the Jardini into the tank he is going to take a while to adjust. When I do large water changes my Jar becomes more passive towards his tankmate (a 9-10" oscar) and is harassed for a few days. If there are no other large aggresive fishes in the tank the Jardini should own it all soon. Just watch out for any major injury and fighting.
