Welcome to Aquaria Central! Don't combine Triggs with Lions (in general never works-depends on the trig and its temperment though). Definitely don't get the Tesselata, they get 6 feet long when adult and will need at least a 200g tank, and they are fish eaters rather than crustacean eaters. Zebra Morays are really nice eels, won't bother tankmates, are crustacean eaters, but they do get clumsy when they get larger (Zebras top about 4 feet) so make sure you have your rock structure well supported. Make sure you have enough rock work in the tank to conceal his entire body if you are to keep him with a Trigg and Puff. Trigg and Puffs can get nippy and as long as the eel can cover his body he will be fine. I would go with a Trigg, the Zebra and one of the smaller puffs. Anyway, hope this helps and good luck.
