RE: serious letter

I don't think Michael is trying to "save the native fishes".   Besides,
stocking a pond isn't going to "save the native fishes" anyway.  He's an
experienced aquarist who struck it rich and wants to have some fun.

From his description, I'm thinking the pond is young, else there would
be fish in it.  This probably hasn't become an important
invertebrate-only ecosystem.  I'll bet the mosquitos are happy there
aren't any fish.

For starters:

When rains come will the pond overflow its banks?

Is there flow through the pond?  Any current?

What about water quality?  Is this a runoff pond which collects motor
oil, anti-freeze, etc?

How deep is it?  What type of substrate does it have?
