and the next meet is nearly here! July 27th will be the next meeting, this will include a table show (many of the fish on show will be for sale from breeders/showers)
you also get to meet the lovely lot of buddies that are VB members. Feel free to come along (bring Jess) and have a look around, the day starts form 12:30 and we have various activities on during the day.
