Pond Boss Forums INTRO Questions & Observations Ok, how about a FH/RES pond?

You should be able to recognize a larger mouth on the warmouth compared to the RES. Also the pectoral fin of the warmouth will extend to noticably shorter than the beginning of the anal fin whereas the pectoral fin of the RES will extend back slightly past the beginning of the anal fin. Pectoral fin shape of RES will be longer and more pointed compared to shorter and more rounded pectoral fin of warmouth.
