Sorry, I forgot to take my camera with me to work yesterday. Some of the toads were still in their feeding tanks (even though I know I fed them yesterday...), so here's a pic of them:
Anyway, to the tadpoles. The set I've got here are juvenile Bombina orientalis, which are probably used in the animal development lab. Their tank's a mess, so they'll be staying in these feeding trays until the cleaning crew is done.
That's what their water looked like before I got there. Yuck! The whole tank was like that...
Here are the tadpoles in their new, clean trays:
I also gave them enough lettuce to tie them over until next time.
