You have a beautiful tank!My system is a 50g display. I currently have a pair of clowns. A tomini tang, a trio of chromis and a royal gramma. I have urchins, emerald crabs, peppermint shrimp, limpets, snails and hermits. My rock work has plenty of nooks and crannies and a lot of places to hide.
The question, could I add a small one spot fox face to my system to help with nuisance algae and everyone live in peace. Also, what are the pros and cons of fox face behavior? I know he will eventually outgrow my system and im ok with trading/upgrading eventually.
From a personality and utilitarian point of view a one spot fox face would be perfect however they tend to grow quickly. My current foxy lived in a 48 x 12 x 18, 55 gallon for 3 months and he was clearly unhappy in there. Always on high alert, camouflaging all the time. Moved him to my 72 x 24 x 29 and he’s happy as a clam. He’s one of the guys in there, hanging with the tang gang.
Can it work for a few months? Maybe. Is it possible that some specimens stay small? Yes. But there are other fish that will give you similar bang for the buck without potentially sacrificing their happiness.
