I am abit worried about one of my guppies, Oscar Wilde. I noticed today it seemed like he had a small nip in his tail, I wouldn't have noticed if not for the pinkish red swelling around it. That's gone down now but I can still see the nip and the slightly reddish tint. This isn't part of his marking, he's a pale blue. I have gone to the pet shop, got some general 'waterlife - treats pin rot & ulcers, pop eye, cloudy eye, red veins, wounds & bacterial infections.'
I did a water change, almost 50% and added the waterlife treatment in. is there anything else I can do ? I know sometimes there's only so much you can do. hopefully I have caught this early.
the tank is about 45 litres, with 16 fish, all males guppies (except two Oto algae suckers) I haven't had any fighting before, no fin nipping, I can't see a particular aggressive male in the lot who could have done this, so not sure what's happened or caused this. I have plants and a piece of wood in the tank, maybe he caught his tail ? He's swimming fine, he's eaten aswell. He is one of the bigger guppies, with probably the 3rd or 4th biggest tail, but he's like a pale blue. I sometimes guppies have tail envy. How long before I might see some results ? the bottle says add 40 mls once a day from two to five days. this seem right ?
here is a picture of the wound / sorry for the poor quality. -
