Last night I noticed one of my male Ellioti looking very tatty, dorsal fin all bloody and torn, today he is barely breathing or moving, just hanging out around the top of the filter. Obviously the flaring and in-fighting between the group has gotten worse as I cant believe anything else caused this, unless the Nicaraguan got in on the squabbles. Im loathed to euthanise, but if he doesnt pick up soon, I fear no other option.
