mmm ... sorry to be a wet blanket but shouldn't you wait a little to introduce a nemmie? ... Your water needs to be very stable and not have too many changes going on in there ... BTA or any nemmie for that matter needs a well established tank and check their lighting and flow requirements thoroughly or you will need lots of tissues if things don't work out ... Bear in mind an unhappy nemmie could spell doom and complete tank wipe out if not the right conditions for it ....
