Red Gill

[jamie20]

Hi all, my name is Ray i have recently set up a 110L/25G tropical fish tank all i have in it at the moment is 2 Loaches and five Danio Zebras one of which i think is a female. My concern is that the female has got one red gill, the Danios seem to be a bit aggresive especially the female, do you think this female has been bitten on the gill or could it be more serious? Anyone have an answer please.

Hello Ray, who registered as Jamie, have you tested your water parameters? It might help if you can provide more info. Setup "recently"...how recently? Did you cycle the filter/tank etc?
