Hi Cheryl,

A couple of reasons:

- are they bullfrog tadpoles? They won't change
until next summer. Some greenfrogs also.

- is it colder in your room this year? Water temperature
is a factor.

- are they getting enough veggie? Too much protein isn't
good for them - what is in the goldfish flakes? spiruluna is
a good food for them or algae wafers. Or you can buy organic romaine
lettuce and freeze it, then feed it. Or good old pond scum.
Their mouths and 'teeth' are meant to scrape algae off surfaces.
When they change then their mouth and gut changes to
become protein eaters.

good luck and let us know what happens!
