if u find that prazi works. then u may wanna hook one up for the p14s. it doesnt hurt only benefits the rays.it drove me nuts when this situation kept happening and happening even with my best efforts with keeping everything as sterile as possible. after i hooked 1 up it has never happened again. another question i was gonna ask was is the male about to loose his barb? they act up the last week before they loose their barbs.
