I have 2 small oscars (4" & 5"). I have had them about a month. All is going well but the smaller one has developed "HOLE IN THE HEAD". I have never seen it on little guys before. I think I better do something quick. I have some other fish in the tank as well that I don't want hurt by treatments. What should I use? Where do I get it? HELP!

I've not had to deal with that yet but read this link from our homepage, I hope it helps.

perhaps your fishes had been exposed to bad water condition
in the lfs or from its origin. keeping your water in tip top
condition will allow it to heal even with out medication. just
increase the temp to 80 deg F, add some pure salt (1 TBS/25 gal)
and create additional aeration to enhance oxygenation.

WILCO & Thanks. Will this have any effect on the other fish in the tank?

Thanks. Love the quote & picture.

Thanks.
