I have got two dats at around 7" in a 125g with a knife fish and a couple of birchirs. Both dats stay very dark and are rather skittish I see everyone else's with lovley gold colours, my ph is around 7.6 and my water quality is pretty much perfect with the temp at about 25. When feeding the dats will dart in an then dart off normally into bits of bog wood then just sit there to digest it with out moving, there's lots of hiding places for them with plants to help break the tank up any ideas.
