Yes they are, and y'all are welcome to all of the bullfrog tadpoles we have out here in the wild! The American Bullfrog (Rana catesbeiana) is an invasive species here in California! It is threatening to wipe out our local baby garters, our smaller frogs, and our baby Western Pond Turtles! Lefty, my one-eyed garter is drooling just feeling the vibtrations of me talking about it.... okay not really, but I had a few beers at a work potluck, and uh, well you know... my fingers are slurring....

Nice pics Wayne. Whats your fish of choice for baby ribbons?

Well I have used rosies in a pinch, guppies and minnows work well too.

A local fishing supplier carries these small shiner minnows that are the same exact creek minnows garters eat in the wild, the ribbon babies like them as well.

Cool, thanks. I've been using guppies for my gulf coast ribbon babies so far. 7 of the 8 are eating. I need to try again this weekend yet.

The one that is not eating yet, try placing the snake and the guppy in a smaller container together.

I found some nice plastic sandwich boxes for a dollar, they work great.

Placing the guppy and the snake in the same small area for a while sometimes will annoy the snake enough that it will eat to make the fish go away.

Took this while feeding chomper today....



These two ladies were relaxing in the log a few days ago....

Usually, but that all depends. There's an interesting adaptation they have. In warmer water with low oxygen, they are prompted to metamorphisis sooner, and at a much smaller size. In cooler water with plenty of oxygen, they can take up to three years before becoming adults, and of course, much larger young frogs. I did a little experiment to prove this, by hatching eggs and keeping them in to different tanks under different conditions. In the warm deoxygenated water, I had tadpoles as young as 3 months old, and only about one inch long, turn into frogs. Their siblings, in the cool oxygenated water just continued to become larger tadpoles. Most turned to frogs during their second year as a large tadpole. A few didn't turn into adults until their 3rd year, and the process (sprouting back legs, then front, etc.) was very slow.

The small one's that turned early, were frogs just one month after sprouting their first legs. Pretty interesting I thought. Sounds like an adaptation that would allow them to survive if the eggs were laid in temporary water that was quickly drying up.


I know, old post, but I thought you might find that interesting. I did.

Great photos, Wayne.
A very beautiful find.

Thanks Steve. First one I have seen in nearly a decade.

Watching this one unfold in person, we are experiencing a dry spell and all the water holes are drying up, so the bullfrog tads are morphing really small and quite early to compensate.
