I realize you're asking about bio-load here, but there's a few things you might not be aware of besides how large some of those fish get.
1. White clouds are cool water fish, max preferred temp of 72ish. Yes, they can live at higher temps, but with a shortened life span and higher chances for illnesses. They're also a minnow that require more swimming space than your 10 gallon can afford them, as their habitat is fast moving streams. I bet they love that powerhead you've got in there and with all that flow from the two filter boxes, they're probably very happy flow-wise. They're one of my absolute favorite freshwater fish, the long finned golden varieties are beautiful to me!
2. Your other fish are warmer water fish.
3. The pleco will only be interested in algae for a limited time while it's younger, then it will be interested in the slime coats of your larger fish, or whole body of smaller fish. Your minnows could start vanishing as the pleco gets larger.
4. It looks a lot like Mondo grass in the right corner of your tank. Mondo grass is not a fully aquatic plant, and it will likely die off in a few months. A certain large petstore sells that labeled as an aquatic plant.
5. You've got a java fern in the center I believe. Eventually those large leaves will sprout little plantlets and the large leaf will start to disintegrate to release them. Just grab the little plants and tie them to a rock or driftwood with cotton thread for them to reattach. They're not really a rooting plant, though they can send little rootlets into substrate. You'll want to ensure the stem-like bit they're growing off of isn't completely buried, or it can rot away.
6. If you're planning more root feeding plants (crypts, swords) then you'll want root tabs in your gravel or to switch out the substrate in favor of a soil based. You'll need to replace root tabs every few months if you want to go that route.
It also looks like you've got more than a few inches of gravel in there? So you've got about 39 fish in less than 10 gallons of water. Probably shouldn't be counting the ghost shrimp as fish, low bioload from them anyway.
The good news is, all the aggression issues you're having are diffused because of so many targets for the aggression, so you're not seeing the results of it. With that huge fishload, you've probably got plenty of nitrates for the plants. The Java moss probably loves your tank.
The bad news is, if you're only changing water when it looks discolored, then you've probably got ammonia in there. Running two filters with carbon should be taking care of discoloration, so your carbon is probably exhausted anyway.
I hope none of this discourages you, you said you knew you were asking for it! Starting off planted put you ahead of the curve as far as water quality goes. Welcome to the planted tank world
the answer is yes, but what is your maintenance schedule etc.? I know my bio load on my SW tank is high but I stay on top of it.
