I like them a lot. They are really fun to feed / watch eat. I'd almost prefer to watch them eat instead my pacmans.. probably because they are just more active and feisty about it. They never refuse food.

They just started calling recently too which is really cool, it surprised me considering their size. I didn't expect them to start calling until they were nearing 2" but they are already. They tend to make a bit of noise when you disturb them too. They don't like being touched at all and are super defensive at first, but they settle down pretty quick once they know you aren't going to harm them.
