What a lovely tank! It reminds me of wading through the creek in a canyon up north as a kid for some reason.Correct, all seems normal from what you told us.
My neighbour who knows nothing about fish once asked me how I knew how much to feed each tank, and I could not answer other than by saying it is something I just learned instinctively.
The photo below is my Amazon flooded forest blackwater tank (without the tinted water but otherwise parameters are exact) which is minimal in plants but has some nice floating pennywort that the hatchetfish love, the pencilfish remain among, and the cories spawn on! This tank was just set up (I moved end of May) in mid-June and the chain sword plant has already sent out a runner with six plants springing up.
You know, I'm relieved to hear about your feeding methods, that's what I've felt I ought to do, but it was hard to be sure with the food bottles and the standard advice telling me to feed them two or three times a day. I've been watching them closely while they're eating - if I give them the "recommended" portion I end up scooping out leftovers with a net later. The molly only seems to want a bite or two of shrimp pellet, since he spends all day cleaning algae off leaves and roots. Maybe the fish and I can do a weekly fasting day together, ha.
I'll have to check pet stores to see if I can find any of those floaters, it's too hot here to ship anything alive right now... thank you for the species recommendations!
Dang, that was a lot of helpful advice in one post, I'll have to bookmark that
