I had 2 cleaner shrimp for the past 3 months and recently (about a month ago) I purchased algae attack pack from LiveAquaria that included a bunch of crabs, snails and a Coral Banded shrimp. A couple of days ago I noticed one of my cleaner was missing, gone, nowhere to be found. No body parts anywhere, nothing. So I didn't think much of it, but last night my other cleaner shrimp was in the tank and today he's gone too! I checked the overflows, the back of the tank, even my sump, nothing, gone!
So my question is, with my other tank mates (see list below), is it possible that something may have eaten them both?
Inverts:
1 Large (about 2") Atlantic Hermit Crab
1 Blood Red Shrimp
1 CBS
1 Arrow Crab
2 Blue Emerald Crabs
various red & blue legged crabs
1 Bali starfish
Fish:
4 Yellow Tangs
Tank:
155g
Params:
PH: 8.2
NO2: 0
NO3: 0
NH3: 0-.25
PO4: 0
Everyone has been living peacfully for the past month or two and I never saw any inverts being aggresive towards each other. I'm sure it's possible that something in my tank ate both of them, but what?
