advice on 55 gallon stocking list

So am currently planning for a 55gallon reef tank that i should be getting up and running in the next few months.Thsi is my second saltwater after starting with a 15 gallon fowlr with only 2 o clownfish in. After two weeks i knew i had to upgrade.

So as far as the stocking list goes :

2 0 clowns
1 firefish
1 mcoskers flasher wrasse
1 algae blenny
1 coral beauty
1 yellow watchman goby

and then possibly a shoal of chromic of 3/4/5


However i have recently been eluded to the possibility of a snowflake eel being reef safe. Does anyone have any ideas on these and if/how i could fit them into my stocking plans as i find them a really intersting addition


Thanks a lot
