Hi, smegforbrains,
Mango does look very happy - and I must say the notion of wrapping paper as a backing is very clever.
The plants look pretty, too, although, speaking as She Who Knows Nothing and Can't See Detail Well On Pics on This Computer, they seem to be still possibly wearing the lead weight wrapping they so often are sold in, at least out here, which, if this is the case, may result in toxins being leached into the water and also quite possibly cause the stems to rot where compressed.
At any rate, this happened to me...
Apparently any rock wool or other absorbant wrapping is likely to be soaked in high-phosphate liquid fertilizers which may trigger algae - potentially something awful in the form of some dread hair algae - and I generally find a black root condition on plants arriving in those, although I may just be
lucky.
Also, some plants don't grow well or even at all if too close to certain others, although I've no idea which with who, so to speak.
Thought I'd better give you a heads up on this, as I'm not the only one to have problems in that situation, and I now invariably remove, as recommended, every possible scrap of any such wrapping from roots/stems prior to adding plants to any tank.
Small rocks, whether temporary or not, work well to hold plants down to root in, typically without damaging the plants or adding damaging metals or other substances to the water.
Of course, you may just be waiting for the arrival of the cave to rearrange things, in which case, never mind.
They do look like a nice mix of plants, and you're lucky, we don't seem to get mixed bags like that at stores out here.
Edit - is it soft green algae?
It may very well have come in with the plants - and do you have phosphate-soaked rockwool in there around the plant roots?
This could be a great excuse to get LOTS of plants, a few lovely little otos, some snails, have a forest, you lucky dog, you!
Some of us would love to have good lighting - what's it work out to per gallon for watts?
(Not that I can sort out different 'watt worths' among the different lighting types.)
Looks like a pretty tall tank, although I'm darned if I recall the gallonage I so recently would have read...
Gawd knows I know nothing - but personally, I wouldn't be in a hurry to change lighting which may be just fine for a planted tank, when so many of us have to replace crappy standard lighting as best we can because they won't keep plants alive.
Also, a 'siesta' of a few hours in the middle of the photo period apparently works wonders to reduce algae.
There are some very nice ways of dealing with edible algae...
