KrazyGeoff Posted February 13, 2014 Report Share Posted February 13, 2014 Fight club :bggrn: This is a fairly typical indication of "pushing each other around" There appear to be two causes that I have noticed. One is using the pectoral fins (side fins) to lock the fish into a cave or crevice and then use the tail to defend the cave or crevice. This one usually also comes with rubbing to the flanks of the fish, near the tail. The other is basically a good old fight using the pectoral fins as a weapon, where one fish will side up to the other fish and then use the pectoral fins to try and push the other fish away. Similar to a forearm bit of pushing with a human, but without any further escalation as there are not fists at the ends of the fish forearm! Nothing to really worry about, another bit of drift wood, or some other place to hide will pretty much sort it out. The redness is blood, happens on the brown bristlenose, but much harder to see due to the brown skin pigment. Cheers Geoff Quote Link to comment Share on other sites More sharing options...
