I currently have a well established 55 all fish Aquarium.
The fish I have are:

Harliquin Tuskfish
Picasso Trigger
Clarks Clown
Dragon Wrasse
Spotted Hawkfish
Arceye Hawkfish
5 Chocolatechip Stars

So far i have had no problems(plenty of filtration)and I am probably remove the hawkfish one the trigger gets bigger. I was just wondering if I could add a fish to help with the algae such as a larger size blenny.
