So far, one of the new 6 inch Datnoid is hiding all of the time. The other one hides but comes out to eat tilapia. They don't seem to care about the little guy at all.
U should be fine I have 3-14" dat in one tank few are over 10" most are 3-10 I have about 10 of them now in one tank they fine won't kill each other. Have some wood in there and have space for them then u good
Thanks! So far it seems fine. One of the 6 inch ones has been hiding for the last 6 days. The former owner told me that one wasn't very social though. The other 6 inch one swims around but he doesn't really swim with the 3 inch one.
