I had 3 babies now it seems that i have 1. My family and i have'nt seen all of them out together in days . Do they bury themselves ? I bought them because i read that they're active and always out . They seemed to be fine for a couple of months. I don't think any of my fish ate them.Ant ideas ?

They are great hiders.
Do you have any decorations with large holes at the bottom, for water to flow in.
They can make their way into some small areas.

Hi, no holes i redecorated for that reason. I have only slate and rock caves driftwood and plants. I can see thru my entire tank at this time thats what puzzles me.At least i now know that they're hiders, thanks. I love these guys sure hopr they re-emerge.
