Here's my current fish:

yellow tang
kole tang
lawnmower blenny
false perc
blue damsel
yellow tail damsel
mystery wrasse
flame hawk
mandarin
5 chromis
2 6" engineer gobys

My questions is, do you think the current bioload is about all I can do or do you think I could safely add more fish? 175G seems like a lot of water so I'm thinking I could add more but I don't want to overdo it.
