Suggestions for last fish to add!
I have a Biocube 14G that currently houses an ocellaris clownfish, yellowtail damsel, fire shrimp, various hermits and snail, and a few mushrooms/zoas. I used to have a tailspot blenny as well, but it died out of no where after a few months. The tank is consistently at 0 for nitrates/nitrites/ammonia. Was hoping for some suggestions for a third and final fish to add that would be ok given my tank size. If needed, I can take the damsel back and reintroduce a new damsel after the other fish has been introduced to the tank to avoid possible aggression. (damsel never had any problems with clown or tail spot blenny).
Any suggestions/feedback/etc. would be much appreciated!
