I love the tank and I can see that hardscape in the back! I recommend moving that big green plant in the middle to the side a bit so the rocks and wood are more visible, or move the rocks and wood forwards a bit and move some plants behind it. Other than that, I can't really say anything else. It will look so good when those live plants start growing and taking up the tank! Its very understocked which is great for the quality of life of the fish. I can't quite tell from the picture but if all of your platys are male, then all of those plants and the rocks will serve as fantastic hiding places to help with aggression. You might want to think about getting a little snail friend to go in there too but that is fully up to you. Most people here will tell you to get a mystery snail and I agree, they are awesome, but I like nerite snails the most personally. They might lay eggs but they won't hatch unless they are in slightly salty water so you will never have to deal with overpopulation. Mystery snail eggs will hatch but they are really easy to spot as they float at the water surface, however I just don't want the risk. But that's all just my opinion, snails aren't necessary at all, unless you want them of course. With all of that aside, best of luck with the tank and I would love to see some progress updates later on! Best wishes, Nele.
