Look up Akskermish i believes thread her ein the eel section for one of the nicest tire tracks Ive ever seen.
And I think almost everyone who keeps spiney eels has had jumpers, sadly. They seem to jump over any "negative" impact on a tank. ie poor water, aggression from tank-mates, inadequete hideing spots.. in a nutshell stress... spineys that are stressed almost always jump, sick ones die.. stressed ones jump.
