40 gallon future

[Fishlover56]

Hiya
at the moment i have one coral beauty and one clownfish in my tank
im doing 4 gallon water change every week
i run a 800 lph hob full of bio media about 1 pound
then i run one of them aquaone hang on protein skimmer
then i had on refuge which is rated for a 60 gal and it has some marine pure block in then the rest is cheato.
my question is there anymore live stock i could add to my tank in the future i have plenty of rock but they would have to be reef safe
many thanks

Sure! How about a blenny or goby and a chromis or firefish? But if it was me I'd be looking into some cool inverts, maybe a brittle or serpent starfish?
