I think you might be right Osiris. Looking at pics, it appears that I have a male. He's really fun to interact with already. He's learned that I'm a reliable food source so he comes begging when he sees me at the tank. he's even started eating bloodworms straight from my hand.
I'm finding conflicting minimum tanks size for them thought. Our profiles say 5 as do several other sites, but just as many say 20. any opinions from some of ya'll that have actually kept them?
