Seeking "oddball" fish recommendations...

[Ostrow]

So, I have an "opening" (lol) for a fish for my 155 display/300 system.

Current inhabitants, all of whom I prefer to survive:

Desjardin Sailfin
Foxface Lo
Radiant Wrasse
Blue Spot Goby
3x Royal Gramma
Clown Goby
6x peppermint shrimp
2 starfish
snails/crabs
Acropora and Montipora of various makes and models

I recently removed a mystery wrasse implicated in the disappearance of several peppermint shrimp

I recently lost a cosmetus wrasse to old age who also was implicated earlier in the loss of the shrimp. Due to intermittent aiptasia blooms, the pepps are needed.

By "oddball" I'm thinking in the cow/frog/leaf/trigger/puffer fish range, but I need not be locked into those categories. Something unusual, cool, and peaceful to the above list. Might be a tricky find...

if you want a peaceful trigger I believe the sargassum is one of the only ones that not only leaves corals alone but it doesn't touch inverts either. mine doesn't really touch anything and is super peaceful.

the mandarin dragonet is also a pretty oddball fish but you need to have a tank established with pods for one of those

Last time I went to Reefwise they had a couple that may interest you...
Jackknife - Equetus lanceolatus
Red Rooster Pygmy Waspfish - Equetus lanceolatus
Wartskin Angler Frogfish - Antennarius maculatus < This one would probably pick off the peppermints, but it is super cool looking!
