OP not sure it's what you're looking for (and there are certainly other considerations with such fish) and I really can't recommend it, but some people have successfully kept a pleco with their Flowerhorn. I've seen others online and some years ago I had this going on with a ZZ Dragon, but it really depends on the personality of the FH (and whether they're smart enough to know that eating the pleco could kill them). So it's basically a roll of the dice.
In the case mentioned the ZZ was definitely aware of the pleco but as long as it didn't get in his way he pretty much left it alone. Another factor was that the pleco was in the tank first -- had it been reversed the ZZ very likely would have gone bonkers.
I eventually gave the pleco to a hotel partner with lots of big ponds, as it was just contributing too much waste and FH already do enough of that themselves -- like others I also think a 75g would be a nice home for just your bonsai.
If you're worried about your fish being bored:
a) one of the best things about FH's is that they're so interactive -- if you 'play' with your fish by moving your finger around the glass sometimes, train it to do loop-to-loops, etc. it will be happier and healthier and get some exercise in the process.
b) some peeps also put a mirror against the glass or in the tank, then let their FH 'fight' its reflection (esp. males for developing their humps), but this should only be done for short periods and maybe not everyday as it can overly stress the fish -- I prefer directly interacting with the fish, they're characters, act like they love you and then try to kill you lol.
