Two days ago I noticed the male turquoise guppie a little saddened. His color fins were pale and seemed bitten(and I know those to blame are the zebrafish(they bullied him). Hopefully he will survive. Right now he is in a quarantine fish tank getting medicine treatment. One thing is sure. The zebras are going to be moved at another tank once he goes back where he came from.
Note. Next morning the guppie died. The zebras got into another fish tank.
