Have you searched everywhere in your tank plecos like to hide. I didn't see mine for weeks, thinking I had looked everywhere it could fit. I was wrong. I have a square clay pot type decoration, it's put in upside down, there are fish shapes cut out. The pleco could fit in there, that is where it had been hiding.
I have a dog named Daisy, she is a husky/lab cross, and an itty bitty Pitty named Maggie
Socks, the orange and white domestic short haired kitty.
A guenia pig that has yet to be named.
3 Bettas in thier own gallon in a half brandysnifter.
I have fire belly newts too.
