Hi there..I have checked all over the place but cant seem to find anyting similar? I " saved" 2 goldfish about 4 months ago from the pet shop while buying dog food ( go figure!) felt sorry for all the comets crammed into the " feeder" tank so 2 came home with me....of course they grew quite rapidly, so, $100 or so later, my 10 cent rescues have now been moved into a 3 gallon tank....they are both just basic comets ( I think?) One is mostly white with a bit of orange on the head ( and pretty blue eyes!) and the other is a copper colour....I just came back from a 1 week vacation leaving them in care of my room mate...I had also just finished a session of tetracycline as the copper one ( renamed " STUBBY") had fin rot...the white one that was pretty chubby is now skinny?...Then I noticed eggs stuck all over the sides of the tank...so he is obviously a she....bringing me to the point of this.....she is extremely red around the base of her body where it meets her tail, it looks very painful although not giving her any problems as she is racing around as usual and eating well. Is this something that would be normal for a fish that has just spawned and is maybe just more noticable due to the fact she is white? ..I did a 50% water change as soon as I came back ( was only away 5 days) but not sure what else to do???
Thanks, and sorry for being so long winded!
