lg comet w/red mark on top of head?
« on: July 02, 2011, 02:05:27 PM »
fish is 3yrs+ and is 12"+ has out grown two tanks & is now now in a 18-20gal. tank outside w/3 2-3"sm. comets was fine until we added a sm. koi from "petco" water from store turned the water cloudy & slime started to grow-koi was dead 3 days latter, org.sm. comets o.k just Lg. comet not looking right w/red mark on head also had some on top of tail and some red lines on tail fin that are now gone, but still see some slime & little white grains on bottom of tank? w/ string like poop:( -doing a water change every day & adding epson salt is helping, fish hang out on bottom not eating as much cut back on food this also is helping to get the water better, we have had some hot days but our water is from a spring well & is crystal clear, have friends in area w/koi ponds only refill every day as needed fish do well! what to do?

Take away the koi from the tank and give him to someone with a pond, or back to the pet shop. You should never keep koi in a tank as they grow to be several feet long. In an "18-20" gallon tank, you shouldn't keep anything else than one comet anyway.

Sorry to hear your koi died; Nossie is correct, they need a ton of space and aren't suited to live in a tank. Your tank is suitable for your 12+ comet only. Epsom salts are good, but I would suggest using non-iodinized salt as well, 3 tablespoons per 10 gallons.  Smiley

Does your fish have a short, compact tail and barbels around the mouth? If so, could be a koi/carp hybrid. If not, it's definitely a comet, and he should be fine in the tank, as long as you'll be changing the water every week Smiley

Good luck with your fish, glad to hear he is a toughy!  Smiley It sounds like the red mark on his head may be blood hemmorhaging due to poor water quality, seeing as it is only there some of the time - not like his natural coloring. It should go away when the water conditions become more stable and he recovers all the way. When I got my nacreous fantail Alabaster, he had some red patches around his mouth that gradually went away...good water for a long period of time will do that.  Wink

Goldiegirl really has a point Smiley Try to do a large water change and see if he perks up. Not a 100% and scrubbing everything, but take out a good 75% and vacuum the gravel real well.

Lol nice one with the hose...we fish people go to extremes to keep predators away from our babies.  Wink and it's good of you to try to keep the heat down; overheated fish = more problems.

Just to be safe, you're not adding a full dose of salt everytime you change the water, right?
Salt doesn't vaporize, so if you'd keep adding salt in full doses, while the water would vaporize, your fish may be hurt from the raised salt levels.

Hope everything will go well from now on Smiley

Plants are fine, take Java fern or anubias which will easily survive the goldfishes' constant nibbling.

But take out the lucky bamboo, it's not an aquarium plant so it will start rotting if you'll keep it submerged :/
