I think your tank is big enough for the Moorii based on your current stocking levels even when fully grown provided you have plenty of filtration. (lovely fish by the way).
Thanks they are nice. Are they not very agressive when fully grown to males of own species or other species.
Have you had any experience with them so far they keep to themselves quite alot in the biggest nicest cave in the tank, they come out every so often. It should be atleast a year until they max out if not more but if they become a problem im sure i wont have a problem rehoming.
