It's PLECO!

I was having a lousy day and needed cheering up so I went to one of my new favorite places.

I brought a jar of pond water over to $petstore for testing and so I would have an excuse to look at more fish.

My pond advisor, M, tested the water and declared it to be perfect. I said I had just wanted to make sure because it was growing more algae lately. She asked if I was ever going to get a Pleco. I said the water might be too hot. She said they can stand up to 85 degrees - and then showed me a Pleco as long as my first finger (meaning the turtle of doom was less likely to eat it).

I bought it.

I think her (?) name is Butt.
