Killed by a RummyNose
I was watching my tank today, and I saw a RCS swimming by, then I saw a rummy nose grab his antenna and hung on to it. He then let go and then bit it again, and swung him around a few times. The RCS finally hit the substrate, and he just sat there, then he went sideways..
I think he lost his antennas, he suffered for a few hours and now he is dead. I see no visible damage other than shaved of antennas. Poor guy.
