Time for a progress update on my 32 Litre "Tree Scape" Tank!
Still no Co2 injection, no Excel, no fertilizers added... and the Hemianthus Callitrichoides (HC) carpet is still growing steadily.
Although i actually do have Co2 injection equipment, chemicals and
fertilizers available to use, i'm now very keen to see how this tank
progresses without the help of those items. It will be an on-going
experiment in using a low-tech/low-maintenance natural approach to plant
I have also added in a group of Danio Margaritatus (aka Celestial Pearl Danio) and Danio Erythromicron
(aka Emerald Dwarf Danio) as the new resident fauna, both are very
similar in size, shape, behavior and habits, often banding together in
small "hunting" packs and patrolling the mid-bottom levels of the tank.
In addition, i spotted many small shrimplets in the tank recently, so
to prevent them from getting sucked into the canister filter, i've also
had to install a stainless steel mesh guard on the filter intake too. :)
Here is a photo of the tank at Week 6:
Notice that the HC carpet on the left side of the tank looks much brighter and more lush than those on the right side?
My guess is that the bogwood piece is perhaps overshadowing that area,
so the growth is slower there. It could also be due to the water
current being better at the left side too (based on the flow direction
of the lily pipe output).
This probably resembles the effect of large trees in nature, where the
areas under them usually have less plant growth, due to the tree canopy
blocking out sunlight and drawing in more nutrients.
The biggest surprise for me is the growth of the Fissidens Fontanus on
the bogwood tree structure, there is definitely a very noticeable
difference in the span of 4 weeks... the fissidens cling to the wood
very securely on their own after just a few weeks and alot of fresh new
growth can be seen sprouting out from the sides of the trunk and
I was expecting the fissidens to grow very slowly, but it turns out that they are actually growing much faster than i expected.
Looks like i don't have to wait too long for a nice lush fissiden tree after all! :)
