Dr. Joe-I will try the barrier idea for sure! I don't know why I didn't think of that, even when I have those tubes that will be perfect...
About the killies-I am not in any club, I collect all my killies localy. I collect fish often for my work-so when our tanks get taken down for any reason, fish end up at my house instead of released back into the wild.
I have never really been interested in the rare killies, I like keeping Florida's natives...It's funny when people ask where I got the fish and I tell them a ditch on the side of the road!
