How should I rearrange it? The things I currently have in there (a big rock, a piece of Malaysian driftwood, and a PVC
tunnel) can really only be configured one way.
Should I buy some new pieces of driftwood or something and add them right before I put the new angel in?
Also, should I have the tank heavily planted? There's probably 10 or so plants in there now, but it's far from heavily planted. Would adding more plants right before I get the angel be enough to confuse my current female angel?
