Well Filiportela and myself managed to get each 4 Dats of Indonesia( 2 of Borneo and 2 of Sumatra each )...they are very small , around 1.5 inches...Mine survived the trip and are in their own tank ( Filipe is still climatizing, last I heard )..
How do I pump this up? Any secrets? also i have 2 thin bar dats that at this age were terrible to one another..should i expect agression between these new midgets?
