I currently have a snowflake eel, Male Blue Throat Trigger, Blue Spotted Puffer, Flame Hawk and Green Bird Wrasse. Is there anything I can add to the tank? I don't think there is but I'm looking for any advice.
Anything added will be trial-and-error, but if you have a deep sand bed (at least 3") you can try nassarius snails; although, your trigger should keep this well stirred. Turbo snails can be tried due to their size along with serpent stars and urchins. Cleaner shrimp may be iffy, depending on whether or not they're accepted for their cleaning ability and not their "yumminess." Sea cucumbers that burrow on/in the sand can be used, but they don't do much.
When I had my snowflake he would not bother my nassarius snails. I`ve never had a trigger so I cant speak for it but they would be OK with the eel anyway. They are also excellent clean up crew members.
You can view many of my fish and corals in my photo albums in my profile.
