Joost, first of all, as to the colors per se, I like the ones I see in the empty tank, at least at the distance seen in the pics. A little more lighting may help us visualize things better and maybe a little closer... but I like the colors as you have them. If you feel you need an additional layer of clear epoxic resin, I would just brush it over the stonework as it is.

If you want the right color of water, the reddish-brown blackwater, all you need is Tetra Blackwater Extract or Kent Blackwater Expert, Catappa leaf extract and the right lighting, warm toned fluorescents, or you might look into the new red LCD lights now on the market:

All you need to do is a little bit of chromatic play to get just the right deep red tea color you want... or throw a pipe from the Ventuari and get some real firewater.

Actually, once you get the right lights, you may not even need to add any tannins and trace elements will be all you need. Though a nice bunch of catappa leaves and the help of the two blackwater products I mention are always beneficial to the fish.

thnx all for the great advices. It is taking me a long time to build, but this is as far as I got now with my Orinoco Biotope:

Tonight I will start filling up the tank with water.


Does anyone know which floating plants are found in the Orinoco (if any) I would like some green along the water surface... Thnx :)

EDIT: somehow on my computer the full width of the pics is not displayed. Here are the links to the pictures in full width:

Hi Joost, quite a project there.

If you use the scroll bars under and next to the pics, you can see your entire pictures.

Thnx Ed :)

Do you happen to know which floating plants or other green around the water surface would be correct to use?

Well, remember there are not really many plants in the altum habitat proper. Branches that come in from the surface is probably more appropriate.

One thing you may consider though is giant vallisneria that will curve over the surface quickly and provide good toplight diffusion.

But take into account, that in general, plants are scarce in the rocky, acid, rather swift and well oxygenated Altum habitat.

Thnx Ed!

I know there aren't many plants to be found. I know that the water is to acidic for plants to survive. That is why I don't want to plant any in the substrate. I just assumed that there would be floating kinds of plants like limnobium laevigatum etc. or vegetation hanging in the water from the banks in some places. But since I haven't actually been there I am not sure. Hence my questions :)

The only problem with using natural floating plants in an altum habitat aquarium is the current. I suppose you can fix the problem simply by directing your current flow in a way that it works, but I once ended up with all the lemna in my filter. Most of the smaller leaved floating plants such as lemna sp., Phyllanthus sp., limnobium sp., etc. will pe pulled into the water column and eventually suctioned by the filter intakes. I didn't bother to try and fix it.

I prefer branches to hang in from above into the surface. To create more light diffusion I use artificial floating plants that can be anchored among the branches. The use of T. catappa leaves and other tropical hardwood leaves can also be used, allowing them to just flow in the current. For the first days they will float and entangle among the subsurface branches, some will stay lodged on to the branches (or you can help them to hang on by piercing them and hooking a leaf onto a branch twig). Eventually the leaves get water logged and they will sink. With time you should take them out, though bacteria will take care of them.

All these details, the color and tannins the dead catappa leaves bring to the water, and even their vanishing skeletal structure bring a very natural ambient to a natural aquarium.

I just bought 10 Pt. Altum for this tank :)

They are wilds, appearantly caught in the Rio Ventuari, near Atabapo.

The ones I got are 8 -10 inches high. (20 -25cm)
They have been in quaranteen for 2 weeks and eat well.
I will pick them up next weekend.

Here are some shots that I took of them in the quaranteen tank.

I bet you cant wait for that drive into Belgium now!
Those fish look like they are worth every penny, they look in mint condition, is it anywhere near Ypres? That's the only place i've really been in Belgium!

That is a great Altum tank and those are very nice Altums.

I must take exception with some of Heiko Bleher's recommendations.
If you want plants do not include any Metynnis or Myleus species. They are plant eating Piranhas.
Also bad plant eaters are all Anostomids.
Furthermore Leporinus fasciatus types get up to 60 cm long in large aquaria and the Anostomids are bad fin nippers. I would also exclude any Chalceus macrolepidotus due to their excessive size and fin eating proclivities.
I found little fault with the other suggestions.

keep in mind that Heiko creates biotopes stocking fish together which are conspecifics in the wild where there is unlimited space and his displays are temporary set ups for exhibitions. What works for up to a week does not necessarily work over the years and with such a large investment in tank and fish I would take the long term view.
