And mick, all of the plants started out as an experiment. Tanks without plants look somehow wrong to me. I tried to place them in corners out of the direct line of the current. Both crypts are in still-ish zones and the limnophila is rooted as far into the front corner as I could manage. As it grows so long, it has grown into the current and seems to get blown around a lot, but is sending down root streamers between the rocks. Don't think any of the long sections have rooted in yet, however.
The crypts are growing slowly (very) and have not sent out any runners, yet.
The windelov was well established on the wood before I put it in the tank, but it too, is out of the direct line of the current. Little bits of it that get knocked off by the barbs (always rummaging around in it) or blown off when it grows too close to the main stream from the powerhead end up trapped in crevasses between the rocks. If they stay there long enough they attach to the rock. I let the ones that float up to the surface root for a bit and then take them out when they're a decent size and tie them to other pieces of wood to start new colonies now and then. My friend at the lfs (where I trade in my angel babies) is always asking me, 'Got any more cool planted wood?' He's a hippy throwback from the 80's with a long blonde ponytail.
I don't do anything special for the plants other than the occasional (and quite irregular) dosing with liquid ferts at a waterchange. One compact fluorescent light strip on top, that is overdue for changing at the moment.
On another note, this morning I fed the tank bloodworms. Within a second all four of the new guys were in the stream, side by side, hunting. They're like lightning catching those worms as they blast off the cube into the stream. I like 'em.
