I just purchased 3 Orino's from Rich which should be here Thursday. I have a 280 gallon that is empty at the moment. I feel I need to get a 10 gallon tank or something for them to grow out before I put them in the big tank, or can I put them in there now? How long should it take before they are a decent size to go in the 280. I also purchased a baby black Aro that I will keep seperate until him and the Orino's can live together without eating each other. I am also waiting for 2 Motoro rays I will put them in the 280 as soon as I get them.
