Thanks BettaFishMummy.
Did not know that anubias don't like to be planted in the substrate. Need to figure something out since the current driftwood is only small. Maybe need to put the bridge back inside and attach the anubias to it. However, you are right, it looks better without the bridge......
What about tying it to something else, like a porcelain 'n' shaped ornament?
A little concerned about adding more plants since the heater has taken quite a bit of space at the other end of the aquarium.
