Big changes!

Today I have received the Vallisneria americana/asiatica. Three bunches, for a total of 10 plants, in good apparent conditions. The plan was to make a little forest in one of the corners, and finally release the remaining glassfishes, prisoners since about 7 months, and hoping that this will save them from the archers attentions.

One problem, still unresolved, is a good way of planting the Vallis: the crown should remain out of the substrate, and no sand allowed among the leaves. That is already quite hard to achieve, but after you trim a bit the roots to prepare the plant, there is no way the stem will remain in place into the substrate. So, at the moment I'm using some lead weights, but I don't have enough, and I'm not even sure the lead won't interfere with the water...

Glassfishes released, one of them panicked or so, hectically swimming vertically, like in convulsions, and inevitably attracted the attention of the closest archer: lifetime out of the nursery, about 30 sec. Not good. After that, the remaining ones (4) behaved, and to my amazement nothing happened: the archers somehow do look at them, but let them go. Better feed them regularly, though...

The other big news is, expecting the glassfishes not to last long (I still don't know how they will possibly catch food in such a large tank), I got 6 lovely Melanotenia boesemani. Beautiful. And I hope, once settled, they will take the archers out from their mangrove hideout. At the moment, it still looks like an empty tank: everybody hidden among the roots. But that's the idea of mangroves, I guess...
