Hah..I have been looking at assassins..for when they multiply..I am hung up on inverts...its new to me. I am just annoyed with fish for now. These guys are way more calm..lol. I originally bought a school of bloodfinned tetra but they were giving me a headache because they were bullying eachother. i know there is some rule about how many males to female ratio but try to tell that to a teenager that doesnt even want to be working at the LFS. And then have him try to decifer which is male and female. Before that it was a load of african cichlids..so yes I like a peaceful tank now..
