Except for the name (I mean, it's almost the Greek spelling for the word fish) I like the idea. I really do, something new and original for Trek, a completely non-humanoid, intelligent lifeform.
Well, that's why I went with that name. I like the sound of it, and I don't think that many folks would catch on to the fact of its origin.
The more I think about it, what if Ic'Thus were the captain? We have never had a truly alien Starfleet captain in Star Trek. Yes, we've had diversity by our standards, but surely even a guy with what we would consider a "handicap" (needing a device like the M.A.R.S. suit to get around) would be able to become captain in Starfleet...
