Just wondering what the lifespan is on metabetaeus lohena aka Alpha Opae Ula? Does anyone here know?

Yes the Alpha's came in. These opae are always on the move. Difficult to get pics. I set up a 10 gallon with a sponge filter. They are considered omnivores but I think I'll push to feed every so often. Has anyone seen theirs feeding on algae like the Opae Ula's? Seems like they like to eat flakes and live food. I have more than I need so might sell off a few. Not sure yet.

Also if you or Odin get the chance, can you measure how long is the biggest one you have? Mine was 15mm.

I took my friends whole community of ML. I think there's more then 30. I set up a 10 gallon & probably only see 4-5 at any given time. Not sure about this now. I think I would rather have less in a 3 gallon. I don't want to put the ML with the opae ula. Breed has been going good and I don't want that to stop. Not sure what I'm going to do yet. I have to admit they are a very cool shrimp. Always on the move it seems.
