almost an year or more ago i got 5 of these, i thought i might get a pair out of these as they were all 2" or so, but i lost one within a week, thats when i moved them from the 100 gallon to the 220 gallon( tank mates 9" mbu and 7"flag tail), one among them grew rapidly and ate the runt of the group, there were 2 smaller ones left, now this big one hates the other two on principle and the size difference is almost double.
