It's 2 months and the bichir still haven't attempted a taste for my datnoid. I've seen them both under the dw, the datnoid always try to push out the bichir hahaI'd keep an eye on the bichir which could possibly try to eat the little dat.The raphael should not be an issue since they usually hide most of the time and are rarely ever seen.
The endli almost ate the raph good thing I saw it immediatly, how a bout a bala shark? would it be an effective cleaner fish like the flagtail?As said the dat and catfish will be fine especially as they are about the same size, but your plarger poly could try to eat the other fish.
