Tinfoil Barbs and Silver Dollars are supposed to be compatible tankmates. I've watched videos with them together.My TFBs disagree. The last time I tried this, the TFBs. would piledrive the SDs into the substrate. They both need space, so partitioning the tank isn't a real option. I'm considering just letting them work it out overnight, instead of an hour or two. I could also add hardscape and plastic plants. The tank is pretty bare. A third option is to move the barbs into the tank with the SDs and break up the territorial behavior. (not my first choice)
Suggestions?
