The general understanding appears to be that Conger Eels are territorial. I've wondered about this as there seems to be some evidence to indicate that either they are not territorial at all of have very small territories, and that similar size eels will live in close proximity to each other. The first time I began to wonder about this was when I read the following article:
http://www.britishcongerclub.org.uk/FEA ... NOTICE.htm
These guys (Mell Russ was one of them) caught 3 eels, any of which would have broke the Irish record, weighing 80, 90 and 101lbs while anchored on a wreck in one visit.
This defies a comment I say some where, where it was suggested you move to another wreck if you catch a Conger as you won't catch a bigger one at the same location.
While in Lahinch last week I visited the Aquatic centre, they have an aprox 8ft square Conger tank with 3 eels about 10lbs each in it. The tank has some pipes set into the back and sides (Front is the viewing glass) where the eels can take refuge, eash one has it's own pipe so they don't seem to mind being together.
I suspect that congers will get territorial over their hole or cave but don't have a problem if another conger takes up residence in another hole or cave close by. What do you guys think?
