I kind of want to do the same thing, but not in a 155. Im buying a 180 as a growout for a black arowana and was wondering if I could keep Dats with in the 180? I was considering p-bass but they just grow to fast!
Also, in two years Im getting a 375 gallon tank (96''longx25''highx36''wide)
My original plan was One black arowana, two silvers, and three p-bass.
But Im starting to really like Dats now.
So I'm wondering how many dats could be kept with three aro's in a 375 and how many dats can be kept with one black arowana in a 180 for two years..
I have also heard dats grow very slow, wich is similar to black arowanas in a way and I think it would make a great combo.
