Stocking a 25 gal

[Leah]

small bluelegged hermits are great you could have a couple
Snails I would add later and lots to choose from nassarius, trochus, astrea
Crabs are cool maybe a small emerald
Not sure if the 2 gobies would get along but one would be okay
the firefish and gramma would be good
in one of my 25 I have a gramma and assessor
hope this helps a little
