Tiger Tail Cucumber in 34G display?

[kinetic]

Anyone with long term success with a tiger tail cucumber in a smaller tank, (like in a 34g display)?

I have very minimal rockwork, so a lot of sand (probably 30 lbs). Most areas are about 2" deep.
Tropic Eden Meso Flakes (2.7mm)
Sand is constantly dirty, needs a good clean.
Total water volume is closer to 45g or more.

Should be okay. I have several including one in a 14 gallon mangrove tank. They mostly feed at night, so if you see it out during the day, it may not be getting enough to eat.
