... rotala is coming in tiny new leaves, not sure why that is, any thoughts would be great! thanks
I have heard somewhere that this might be caused by low co2 levels. We should wait for someone else to weigh in on this though as I am no expert.
Youve got some good lookin growth there though. If I were to do anything to it, I would try to trim/replant make it look more defined. It looks cool, but it seems awful busy to me. Things should be a bit more compact and in their place. Empty space isn't empty. Empty space has purpose. I, like someone above me, don't particularly like whichever carpeting plant that one is, but thats just me.
It all kind of depends on what you're trying to go for, but if you rescape it, just think about exactly where you want everything to be, give it a purpose for being where it is.
I would try to add some perceived depth as well. I'm not sure how much hardscape you actually have in there, but creating empty areas helps to create that illusion of extra space.
Its all up to you though. If you like it the way it is, keep it! If you want to add more hardscape, give it a try! If you dont want to try to re-scape in a day you can setup an emersed tank or just a bucket with a light for the plants. Dont be afraid of change.
