Snowflake Moray Eel + ?

I came across these eels co-habitating while diving in Ambon. I recognise the lower of the two as Echidna nebulosa, but not the top eel. There were many instances of pairs of eels like this living together, which leads me to believe the two forms might be sexual variation, or perhaps the top one might be juvenile form, but I can't seem to find any references to verify this.

Anyone have any insight?

Cheers,

Perhaps a Bar-Tail or Bar-Finned moray?? Gymnothorax zonipectus Terrific pic BTW!!

As you mentioned, saw quite a bit of this going on in Ambons harbor when I visited in the spring. Perhaps a lack of appropriate housing, or just enjoys the company??

Also saw it co-habitating with the White Eyed Moray, Siderea thrsoidea, from Ambon as well.

Thanks!

Gymnothorax zonipectus looks like it might be right. Still puzzled by why there were so many co-habitating eels. Haven't ever noticed it elsewhere.

Cheers,

Saw this unlikely trio on the El Dorado House Reef near Dumagette in the Philippines.
