Finally some new pictures and the tank is looking great! The addition of more sand definitely helps because it feels more natural and it also makes it safer by providing more cushion for the bigger rocks in there. I'm glad that many people here like the set up but I believe that you can do better

If I had a say in it, the aquascaping looks a bit messy. Perhaps grouping the rocks together to form monuments, I'd say around 3 main groups, then just a touch of rock here and there. That's all I'll say for now, since it's not all cleared up yet, hahaha. This is just my initial opinion though, I may actually like it after it sinks in.
I noticed the algae on your driftwoods, that's pretty crazy. I would suggest having blinds, or anything that blocks sunlight, for your window since this is probably the cause of your algae problems. I'm not sure if you're willing to spend but some people fix the problem with a UV sterilizer, which can be placed in the sump. Hopefully your plants are still doing alright because moving them while not fully established can kill the plant(considering they haven't been in there for a good amount of time yet). Plants get stressed also.
The fish, like you said, are growing at an alarming rate! Their colors are definitely starting to pop out and shine

I'm surprised by how much they've grown, really great job with them my friend! What's their diet like? I hope you're not stressing them too much with all the renovations and changes
I like the direction you're going, so please keep the updates coming!
