Those guys are awesome...if I knew anything about keeping salt I would definitely have some eels.
Thanks!
Salt's easier then fresh if you ask me...... Get a giant skimmer, lots of live rock, change the water every other month or so, and the rest is pretty easy....
The more eels there are in the tank the crazier they get at feeding time- be ready with a mediation stick.
Over feed and they'll puke- not much in the hobby rivals this level of foul, don't recommend it.
Keep hands out of tank.
VERY easy to enjoy cause they aren't demanding, seem tough as nails, the maintenance schedule and mortality rates are both a fraction what my fresh stuff has been.
