Hello is it normal for my 1" indonesian tiger datnoid to try to ram and sometimes try to nip the fins or sides of my feeding cichlids when some of them got some pieces of lil raw shrimp in them? I ask because my lil guy is always ramming and nipping (no rip fins due to what I think is no teeth?) the sides of all of my larger cichlids....he even tried to take the shrimp out of the mouth of my large male umbee and wild caught male dovii's! which is like
The cichlids don't mind him being in the tank with them all as he doesn't really get in the way unless he chases some piece of shrimp rolling down into one of my cichlids territory where my cichlids will chase him out of the way...Any opinions of young indo datnoids being aggressive during feeding and when done with feeding?

The fish they are with aren't even aggressive...at least not yet.
