AAF you obviously should make the tank livable and get the inhabitants squared away first, but some anubias would look nice on those rocks! I found some at Petsmart for a pretty low price, they were in the dry tube container thingys. (Read the label, it says wether they are anubias or something else) So far mine have done great, I rubber band then to decorations and then remove the bands after they've become attached on their own.
yea i might move the hygro and anubius from my 20 gallon to the 55 i just dont know how they would do in there, but we'll see. i really wanna put some crypts and a sword in there but dont know how the parrot would do with them.
