Snake - caught 2 years ago, about 2 ft long, garter, never found out what kind exactly, but It doesn't matter. Male.
Tadpoles - Free from petco, came in on a shipment of goldfish and they ended up giving them to me. I just redid their little tank completely. Originally I had a gravel slope so when they had legs they could get out onto the land, but, they just messed it up. I've since removed all gravel, and used 3 large rocks on 1 side , with part of a rock protruding from the water. Good slope for them. The smaller (1st picture) has visible legs coming in, shouldn't be too long until I have a froggy! Second is a bullfrog.
The minnows were the 5 smallest minnows from my ACF tank, out of a group of about 50, so I moved them into this little tank to help it look more complete.
