I don't know. Is there a substitute for killifish? Thanks for the offer. I'll think about it. I like pickerel because try look cool and they put up a fight. I was ping to get SmB but I think they won't survive. Can you tell me how many gsh, cp, crayfish, fhm, and killi or the sub? Also web should I stock them like 10 gsh in June 2013 a an example.
