African dwarf frogs and plecos?

[VictoriaZ]

I have a tank with 3 frogs. I added a pleco to it about 9 days ago. I watched for about 30-45 min they were all fine. Well I haven't seen him since. I flipped everything over moved stuff and still no sign of him. Is it possible my frogs ate him?

Plecos hide most of the time, you might see him more active at night.
How big is your tank? What size is the pleco vs the frogs. What species is the pleco?
Frogs can only eat what fits in their mouths.

Those are African Dwarf Frogs, I can guarantee they did NOT eat it. Plecos hide well so I am pretty much sure he's in there somewhere
