you might want to buy or go to the library or your lfs could have a copy of marine fishes by scott w. micheal..great book and all of us should have a copy,although the pic in here..( of a convict blenny) is of a juv.w/ its stripes horizontal,but as it matures stripes are vertical and wavey like..everyone who seen mine at first says wow theres an eel in there..they are very hardy and suggest you make sure your rocks are on bottom of the tank,otherwise the "worm" will dig underneath and could cause an avalanche..I had mine in a cc tank for a while then changed over to a dsb and its personality tripled..good luck
