Q about plant growth in "re-started" tank
I've got a 30gal that I'm bringing back to a low-tech planted tank after a couple of years of basically no lighting. It's been inhabited by a few Australian native fish that enjoyed the "darkness" in that time. But I got a couple of Ambulia cuttings a couple of weeks ago and with the roughly 2wpg of light they grew quickly, getting nicely colored at the tops. But they've stopped growing upwards and have been branching profusely and look really healthy. I was just wondering if this is a good sign or a bad one. Every other time I'd grown ambulia it would either grow quickly and spindly towards the light, or melt. But they'd never branch much from the lower stems due to what I thought was inadequate light. There's also a sword in there that's putting up a new leaf every day. So is this a sign of balance between light, nutrients etc? It's just in my limited experience I've never seen ambulia stop growing upwards and putting all it's energy into side shoots, and look healthy at the same time.
