can guppys tails grow back , cos my small male guppys tail has been bitten and so has hes side fin . He seems happy enuff and swimming about ok Sorry if this sounds such a silly question )
yes.........they do,
but I have one that was bit off as a baby....and his brothers have huge tails...and his has been very slow to grow back...they are adults now, and his is at about 1/2 the size of the others.
When guppies lose their tails many times they can get fin rot which can end up killing the fish. I had a guppy whose tail was nipped and then just started disintegrating.
