the other two are getting along fine. however i watched the bigger one eat a bloodworm then spit it out. idk what to do anymore. im not giving up on them but i think once i remove the tetras things will be calm. maybe there is something going on with having more than one in the tank that they arent interested in the food. i really dont know. but ive seen tetras of all sizes in my tank go after my knifefish, and i cant have that happening. im too attached. but i got some small feeder blocks to tide things over with them, making it so they have something in their system to live on until i find a clear answer after my tetras are out. besides i wanted more angelfish anyways. but the one i have now is really docile, like he minds he own very well. i still dont understand why they wont eat, even when they know that the food is there, hoping that removing the fin nippers will solve problem.
