Hee thanks! I'm thinking of either Limnophilia Vietnam, or maybe blxya; the long leaves would be a better contrast and blxya has a yellowish/reddish tinge, which I prefer to staurogyne's green in this case. Just got hands on some new rocks and can't resist tweaking the hardscape as well. I removed the medium left rock and replanted the entire mid. I realized that my foreground was unnecessarily large, and thus intend to push out the mid, with some additional layers for added complexity. Replanted the arcuata at the back to match the growth rates of the now-redone mid ground. Will post pics when the dust has settled.

Another thing that I realized along the way is that the variegated AR gets quite large. Not sure to force-prune it to be smaller or limit it to only perhaps a couple of stalks on the left side.

This thread was very enjoyable. I like your plant usage and how your tank has evolved over time. Very nice work.

On another note, I'm very interested in your low-tech tanks. I'm sure other members are curious as to how you created the low-tech tanks as well. Maybe create a new journal?

Love your 47g. The composition and plants health is as good as it gets. Well done mate!

Hmm I should do this, been a bit tardy in keeping track of the low tech tanks. I think the setup matters quite a bit, because there are fewer factors to manipulate in a low tech setup, but I also wanted to do a bit more experimentation before giving recommendations to people; so I've been trying on tanks with slightly different dimensions and soils.

All these tanks are so nice looking. I have a question about the Ludwigia sp red in the 47 gal. How do you keep it so small? I understand it's probably not that way all the time, just looking for any tips in general on how to prune L species. Mine get so out of control! Do you just re-plant the tops on a regular basis, or what exactly? Thanks.

Thanks for stopping by! Hmm It's a combination of trimming off the tops to a height that I want, and pre-emptively pinching/cutting off tips that start to grow towards a direction that I don't want it spreading to. For L. sp red, the rooted stem is quite strong if its healthy, and the top can be trimmed off repeated; side shoots sprout fast. The whole bunch in the 47g are branches that come off from about 4 mother stems that root into the substrate. I felt that the trimming for the L. sp red is actually poorly done in the pics compared to the L. Arcuata; it can be contoured in a very exact manner, but I must have missed it when I took this set of pics.

About every 4 months I allow the current batch to grow longer, then do a replanting of tops (where the top node to bottom has no branching).

I think that trimming and allowing side shoots to sprout allows more self-organization (because the plant will grow in a way that doesn't shade itself that much), it makes for a neater, denser bush. Replanting tops kinda resets the plant form to be competitive against surrounding plants. In the search for neater tanks I've been doing alot more pruning and almost no replanting for tops (until after many months). Just a theory based on observation though. It seems to apply to other plants as well. The effect is most apparent in the Ludwigia arcuata (orange background bush); where the dense bush must be achieved through trimming and allowing the side shoots to self-organize to fill up the space. If I just grabbed a bunch of them and planted them side by side, they'll grow in a vertical competitive manner instead of spreading out. I've been wanting to do a video to demonstrate this (because people don't seem to talk about it much) , so I've replanted the entire middle of the tank (start from scratch with sparse stems) and pruned it into a bush like in the pics over the past few weeks. The bushes have grown back in over the past month though, so in a week or so I'll finish my video.

Using an older set of pics to illustrate:
When background stems are planted individually, abeit densely... they each struggle to outgrow the neighbour:


After allowing it to grow out further, before doing a very aggressive trim:


After it has grown out; with self-organization with respect to neighbouring plants:


I know you were asking about L. sp red. But the pruning technique is similar, except that Sp red spreads sideways quite abit more than L. Arcuata. I'm thinking of trying a large pruned sp. Red background for the next tank though Hmm...

That last post was very useful information. You right, people don't really talk about this but I think it's the secret to make a "good" tank "great". I would love to see a video demonstrate along with a time lapse show the plant behaviors.

Great topic!

Great info man, thanks. Effective pruning for various looks is the main skill Im trying to learn right now, and you dont see the finer points discussed very often. I never realized the part about side shoots re-growing in a non-competitive manner, but it makes perfect sense (and is obvious now that I know what Im seeing) I look forward to your video on the subject.

Dude, that was one of the most helpful posts on pruning I've ever seen.

And I've never overly thought about it but it seems like it's make sense. I take it as well that using side shoots as opposed to replanting tops would also serve to make trimming easier, as if the plant isn't becoming multiple competing plants it probably does not grow upwards as much or shade everything ever right?

Thanks man, yeah that's what I think happens. Even downoi exhibits this in an interesting manner. However, depending on how the plant growth shoots form, not all are suitable for pruning into dense bush form. Rotala rotundifolia/wallichi, Hemianthus glomeratus, Ludwigia arcuata/brevipes, Limnophila aromatic/vietnam are some examples of plants suitable for dense background bushes. Ludwigia repens is one of the worst; it grows wide and open with large flattish leaves. Some others like Rotala macrandra/Ludwigia pantanal prefer to be unshaded, and doesn't form alot of side shoots (and look nicer with a single large shoot).

I agree about L. Repens. They just don't cooporate, ever! lol

The first video of the trimming/pruning series is done; for you guys reading these posts there is nothing new... I think. I just transferred the info here into video format; the actual trimming vid will be done probably within these 2 weeks

Great thread. Some very good information here. Will be revisiting when I setup a low tech tank
