Personally, for a "wet pet" fish, I'd get something aggressive that will attack you through the glass as well as beg for food. Amphilophus species like the midas cichlid would be a good choice. Plenty of less common CA cichlids that would work, like: tetracanthus, istlanum, motaguense, lyonsi, plenty more. I would see what you have available to you and do research on them. Most of these fish won't bother a pleco, especially if you keep them together from a smaller size and grow them up together.
How about a paratilapia polleni? They aren't too hard to find. Mine is probably one of my favorite fish.
Where you live? Lol
I have an Arowana I am dying to get rid of lol
Get a Blue Panaque Pleco.
And a couple Oscars.
Think you could fit about 5 Oscars in there. But I don't know for sure.

Looking through those, I really like the greenish/blue version of the Istlanum. Would a male Istlanum be ok with the Pleco? I'm having a hard time finding the answer of that through google


Dude it's a 4 ft tank
What kind of personality do they have (other than mean haha)? I really enjoy the look of this fish
Mine begs for food every time I come into the room. Not shy, never hides, always out and in your face. When I sit for a while and he loses interest in me, he is constantly picking at the plants and rocks around the tank. He likes to dig all the sand out from under his log and pile it in one spot. Pretty typical cichlid stuff, but for a Solo fish, that's the type of personality I'd look for.
I have not kept mota's, though they are on my wishlist. From what I have read, I believe the info I gave you about istlanum would apply to a motaguense as well. Nasty, good fish to keep alone or in a pair, lots of personality.What do you know about the motaguense? That one is rather striking to me as well
