I have a big tank with 10+ fish. I have mostly goldfish in there and 3 Koi fish.

About 3 days ago, their usual foods ran out, so we had to feed them a different brand (pellet).

I haven't washed my fishtank in months now and I see the the build up of something green looking, like dunk and other craps.

I then notice this morning that one of my fishtank lighting had fell into the tank (damn cat). It was plugged into the wall, but I don't think it was turned on but I think that might not be the cause.

I then started to notice one of my biggest koi fish (1 feet in lenght) started floating upside-down and couldn't swim well.

It was if he was trying to get out of the water but was weak. I immediately changed the water and put the sick-looking koi in a separate tank (a HDPE Plastic Bottle and it's big too so it held him with little room to move).

He now stopped floating upside-down, but still look weary and doesn't move much.

$5-10 reward for the solution! I don't want him to die!

I don't know what other fish you have in your tank, so I don't know about them, but since I raise koi, myself, I can at least tell you what you can do to ensure the health of your koi right now: Start with a partial water change, or, if you want to remove all three to a separate tank, that's fine. Try to put at least "some" of their original tank's water in the new tank, though, to lessen the shock of being moved and to ensure that whatever you are using for filtration will have the proper bacteria to get up and running. Test your water - you want your ammonia and nitrites to be at 0, and your nitrates no more than 20 ppm. It is worth it to test - take care of the water, and the fish take care of themselves. You can keep changing 20-30% (certainly nor more than 50%) water out daily until you reach the desired parameters.

Also, you can s-l-o-w-l-y warm up your koi, no more than 1 degree (F) per hour, to the mid to upper 70's (no higher than 86F, no matter what, though, or you'll end up with fish stew!).

Once you are sure your water quality is decent, add Pro-Form C OR Dimilin (but not both) AND Praziquantel to the tank, following dosing instructions for the size, etc. Prazi plus one of the other medications will kill just about every parasite known to koi. Once you have finished dosing the fish with the Prazi and either the Pro-Form C or Dimilin, add salt to your tank (epsom or pond or aquarium salts - NOT table salt and nothing containing iodine) to .3% (you can go as high as .6% if you don't have plants).

There are lots of on-line dosage calculators on the web that can tell you how much salt this would be for your tank. Also, Pro-Form C, Prazi, and Dimilin are all available on-line. I have also seen Pro-Form C and Dimilin in stores like Petco and Petsmart, and Prazi in the pond care section of my local garden center. The Prazi is expensive but it is SOoooo worth it!

Finally, I would also start feeding a medicated food like Medikoi. This should help prevent any bacterial infections that might be secondary to the parasites that the medications will treat, or fungus that the salt should prevent. If you have a really bad bacterial problem, though (like if there are red spots or ulcers on the fish, or red, raised, bumpy lines in the fins - indicators of septicemia/sepsis) you will probably need to get something like AP Ponds anti-bacterial medicine, also available in pet stores and garden centers (and on-line, of course).

The above steps should prevent/cure just about anything disease-wise (fungal, parasitic, or bacterial) that could be affecting your koi. However, it won't do anything about injury, which may have happened if your lighting actually fell into the tank. The fish could have actually received an electrical shock (it is not uncommon). If he can eat enough to get by while he recovers from this on his own, he may survive, and for this reason, smaller fish usually fare better than larger fish. Just give him pristine living conditions (remember to take care of the water! If you do that, the fish can take care of themselves!) and offer high- quality food that he can easily get to on the bottom if he is having trouble swimming up to the top.

Finally, check out www.koivet.com. It is the best website I've ever seen for information regarding the care and keeping of koi. It is run by a veterinarian who specializes in koi and goldfish and it is really good - it can answer a lot of your questions, I'm sure.

Hope this helps - e-mail me if you have any questions. Good luck!

when i was looking up koi fish and the diseases that may occur, i come across some options, whether to treat the effected fish of the whole tank environment. as outlined below

.V.

Overfeeding, high stress environment, or toxic water can lead to unhealthy koi and dangerous bacteria levels.
First, you must decide whether or not to treat the sick fish or the entire pond. Quarantining a fish will keep parasites and viruses from contaminating the entire pond. This may be unreasonable since a separate tank would be required. Most koi meds are not harmful to healthy fish, just be sure to follow exact instructions when administering treatments.

Koi injections are only available through Koi stores and are given by professionals. Koi medicating can be intimidating, but is often a very simple procedure of just adding the medication to the water.

have you contacted someone about the problem yet.. because i believe that your unhealthy fish my be able to recover if action is taken promptly.

Woah! Well, fist, with 10 plus fish, you need a 100 gallon tank -- and actually larger if three are koi! And you say you haven't cleaned the tank in months?? Of course they're sick. Clean the water, but don't change all of it or you have to cycle again. If the fishy has swimbladder, then just stop feeding for two days. I hope they get better soon! (ps, that does sound like it could be swimbladder, so I would feed maybe a few of the insides of peas, and then starve for like two days. But make sure you have like a 200 gallon for those biggies, and you could already have that size.

how large is your tank?
20% of the water should be changed at least 2 times a month.
although with koi and golds more water changes would help.
the light in the tank will not hurt the fish.
koi probably has bloat, which is most likely caused by inhaling air when eating floating food.
with the combination of poor water quality severely stressed out the koi.
it is very difficult to tell with out being able to see it.
do you add any Freshwater aquarium salt,
koi and goldfish tend to like that ( with a pH of about 7.5, but usually they are not picky)

I'm really not surprised that your fish get sick, since you haven't cleaned your tank in months

You're suppose to do a weekly partial waterchange of 25% with a gravelsiphon

Feed them only what they will eat in under 2 min twice a day

The green you see in your tank is algae, caused by to much lightning, not cleaning your tank, feeding to much,

The best way to get rid of green algae is by covering your tank with a blanket for at least 3-5 days, that no light can get to it



Hope that helps
Good luck
