Bullfrog slowing down for the Winter?

[herpdoc]

-how long have you had this bullfrog? in particular, is this the first winter you've had it? (i'd get more worried if it's not the first winter and it hasn't done this before)
-are you living in an area where frogs normally overwinter and is this where this frog is from?
-is the ambient temp lower now than it normally is?

-my frogs have generally been active during the winter, albeit less. the frogs we use in the lab also tend to still be active in the winter (eat, hop, etc)...until of course they are sacrificed!

Hi Caspian,
You were so helpful to me about year ago with my American bullfroglet. My frog is now about a year as a frog (she'd been a tadpole that we raised).Anyways,she is acting very lethargic too and barely eating. I share your concerns but have felt it must be due to Winter, since she appears to be otherwise healthy Does your frog have a slimy viscous film on his lower body? Mine does and I'm not sure what that is about.

Ive had the frog since she was a tadpole about 2 years ago. She became a frog in May 2013. I don't remember her behaving this way last winter. I live in Southern California and the weather is quite temperate. It hasn't been very cold yet this season.

The difference between last winter and this winter is that before she was small enough to hide mostly submerged under rocks. Now, she is large enough that she can't fit under the rocks. We have her in a 90 gallon aquarium that is maybe 60% water and 40% rocks. She shares the tank with 6 small goldfish that were supposed to be feeder fish but she's left them alone. She used to eagerly eat crickets when she was more surrounded by water. Now the crickets hide in the rocks since she is slow to try to catch them. I haven't seen her actually eat a cricket or a meal worm for a long time. Do you need to know anything else?
