Cute! They look like one of my little guys. I have two that are around 3 months but one is smaller and the size of those lil guys.
I love my clowns. The little guy is a tough a** and always swims over to anything I move in the tank, or to me when I walk by, but the second my hand is in the tank, he swims away and hides, lol. He tried "hosting" my xenia for a minute yesterday and I was like "What are you doing?!" and he swam away, lol. I wish one if not both would host my frogspawn, but I guess maybe they're too young for that, or just don't want to.
