Fish Ideas for water box 20 AIO

[Harry g]

I think my yasha goby sadly passed away, or atleast I think so, I haven’t seen her in 4 days now, and the last time I saw her she ate a piece of frozen food which no other fish seems to touch and now I haven’t been able to find her, on top of that I just moved 1200 miles with her in a 5g bucket and all my fish were in a 7g tub holding tank temporarily so I’m guessing she’s dead.

I was wondering if anybody has any ideas for a replacement fish, or also if I could get a little advice on getting a biota mandarin in here?

I currently have two clowns and a bangai cardinal.

Mandarin would be tough, even if it's frozen food/pellet trained (IMO)
Another goby (watchmen are cool) would be fun!

This is a goby that's not seen much. Its in my 15. Transparent cave goby. The black spots are its internal organs.
