Best “replacement” fish?

[i cant think]

I know this is rather cruel to do and think of them as replacing fish however I know my Blue Star Leopard and Naoko Fairy Wrasses will eventually get too big. I’m going with a goby dominated tank and have one VERY small goby. I would like something that isn’t harmful to small fish so I was thinking to stay in the safe side a small goby or two would be best. Here’s my current permanent stock:

- Black Clown Goby
- Griessinger Goby
- Hectors Goby
- Yasha Goby
- Linear Blenny
- Pink Streak Wrasse

Now, I’m on the fenc between:
- Another goby or two
- a Possum wrasse

Any other ideas would be fantastic!!

Striped dottyback (resembles a cleaner wrasse) and royal gramma.

dottybacks can be bullies
