HI, i bought some gupies at the weekend from a reputable fish store and have had two die since. I would be very grateful for any advice or ideas as to why they may have died. I thought it may be stress or pH shock, but others all seem fine at the moment, except the remaining red guppy which is developing black lesions on its tail, the dead ones have very little or no black lesions. tetras seem fine but may be becoming a little lethargic but might be becoming paranoid! i cant find info on these black markings on the tail and wether they are significant. (see pic)
