You are truly prescient, JHAP! Those GF have already started congregating together in various places around the tank and when the PSBG swim by, I'm almost certain that I hear the GF taunting them, saying stuff like this is our hood, you better take those colors off when you come through here, etc. You know the sort of stuff - we've all seen the movies. Being from Cali, you're certainly familiar with MS13, the very violent gang. I swear that earlier today, I saw GF31 eaten into the algae on one of the rocks in the tank. The PSBG have not hung out there since. I think they're catching on to the power of their superior numbers over a couple of real pansies. By the way, I still have 11 GF31 members in the tank. The PSBG did not touch a single one of them last night. Pathetic, but I guess they just don't want to get involved in something they can't finish.
