Experimenting is very advisable. That's how you learn what can go with what generally. The only dats I had that hated them were the big eaters with big stomachs and big attitudes. The dats that were not in charge with consumed by the thought of getting attacked by the bigger dats so they left the cichlids alone..I strongly recommend trying things out..you have plenty of time before the dats get dangerous, but just keep an eye on feedings. Dats can suffer from tentative feedings when the threat of an angry cichlid is around and will have lackluster growth because of it..If all fish are feeding as they should, no need to worry now
