Hi, I got a dwarf frog about a month ago and so far it's been awesome. My friend bought it for me at a size of about 1 1/2 of an inch so if I'm correct it's an adult already. I wanted to buy another one, however the only ones they sell at the pet store now consists of frogs ranging from about 1/2 of an inch to 1 inch in size. At one point I put in a snail and my frog immediately attacked it as soon as it came out and just gave it away to my friend.
My question is would it be safe to put another dwarf frog smaller than the one I have now?
Advice is appreciated
Additional information:
3 1/2 gallon tank
Sand bottom
3 plants to be exact
Also new to the forums and first time owning a frog
