Question
Having just cleaned the pond,I have notices 5 frogs-are they harmful to the fish or can they cohabit

Answer
I have many frogs and fish together in my ponds without problems.  Do you know what species of frog that they are?  How big are they?  How big are the fish and what species?  How big is the pond.  The only frogs that really cause problems and will eat small fish are adult bullfrogs.

Good luck!
