I have a pond that is muddy and took a net to it the other day and would catch 1-5 crawdads with each drag through the water.

Now what I want to know is how likely is it this is the reason the pond is so muddy?

Also would RES do well in the pond since it is muddy, I had thought about adding some to it since there are not very many fish if any at all in the pond.

It is a small pond and thought it may be good to grow some RES out in it with all the crawfish and I am sure snails are in there as well.

Or should I consider a different fish?

Please let me know you thoughts.
