Melafix.. Weirdness Happening

so my fish almost died two days ago due to a big spike in amonnia levels or something.. i found one fish which was almost a black color, basically be envolped in some kind of white looking slime and looking very thin with eyes sunken in and llooked like he was going to die any minute.. the other three looked ok, but recently one of them too started looking kind of sick.. anyways i did a 90% water change knowing that i was probably going tol throw my cycle away but i didnt care as long as i could save the fish.. i went to the pet store and explained my situation to them, and they suggested i put salt in aquarium but i felt i needed something a little bit harsher to save my fish from being whiped out completely.. so the guy suggested i give melafix for about a week..

well as soon as i gave it, probably within two hours the black fish ended up looking a little bit.. and so far its working in positive ways.. but as soon as i add that solution to the water all the fish act weird as in.. looking like their chocking on something.. and two of the other fish end up looking really bloated like their going to burst, the other two look normal.. then all 4 swim at the top near the waters surface for about 1hr.. then seems to return to semi normal behavior.. i was wondering if this is normal for people who use melafix?

also because of the majolr water change i did.. im checking my water aroound 3 times a day and changing 25-30% of the water as soon as amonnia spiked to 0.25.. all water parameters are perfect due to constant monitering.. because i dont want the fish to die.. but im curious about this melafix.. does your fish act weird wen u use it?

This never happens to me when I use Melafix. It should never have this affect.

Can you answer the questions from the top of the page so we can get a more exact idea of what's going on in your tank?

[*]Test Results for the Following:

[*]Ammonia Level? 0.00 - 0.25 in about 6-8hrs.. then i change 25-30% of water

[*]Nitrite Level? 0

[*]Nitrate level? 10-20

[*]Ph Level, Tank (If possible, KH, GH and chloramines)? 7.8

[*]Ph Level, Tap (If possible, KH, GH and chloramines)? 7.8

[*]Brand of test-kit used and whether strips or drops? api test tube kits

[*]Water temperature? 26C

[*]Tank size (how many gals.) and how long has it been running? 55g.. for over 2 yrs.. but now its probably recycling itsself

[*]What is the name and size of the filter(s)? two aquaclears 100..

[*]How often do you change the water and how much? as soon as amonia gets to 0.25-0.50

[*]How many fish in the tank and their size? 4 baby koi ( 1.5 inches ) and a pleco (5inch?)

[*]What kind of water additives or conditioners? API water decholirantor with stress coat stuff

[*]What do you feed your fish and how often? sho koi pelletts.. i feed one pellet at a time untill their all to full to come up.. about 2-3 times a day if they can eat

[*]Any new fish added to the tank? yes

[*]Any medications added to the tank? melafix and cure ick

[*]Any unusual findings on the fish such as "grains of salt," bloody streaks, frayed fins or fungus? extra slime coating, fungus probably.. tail fins slightly red

[*]Any unusual behavior like staying at the bottom, not eating, etc.? flashing, bottom laying.. one fish looked half dead.. swimming at the top corner of tank.. excessive gill breathing

now before i get critized for having koi in the tank.. i just want everyone to know that i do have a pond in my backyard.. and since my fish like to eat their babies after they spawned i managed to find these 4 little guys before their parents got to them.. so im only keeping them indoors untill next spring when they get about 6 or 12 inches.. then releasing them in the pond

Have you done anything to the tank that would cause it to recycle itself? It seems very suspicious that it randomly hit a bump.

Why did you add CureIck?

The "extra slime coating" needs more clarification, please. It most likely is not fungus as fungus is relatively rare in closed environments or ponds. Unless you have really stagnant water...

Pictures would be great.

Also, how old are these fry?

i moved out some of the bigger fish i had before in the pond and forgot to check the filters to see if they needed cleaning.. put the new fish in and within a week and a half i started seeing one fish thats pretty much black in color.. change coloration.. looking dark grey, then light gray.. almost a white color all around.. with eyes sunken in and the fish looking very starved.. clamped fins.. and breathing fast , laying at the bottom of tank near air bubbles or being very lethargic.. all of the other 3 seemed fine.. untill abut 3 days ago when i saw another fish bottom sitting and becoming discolored with an opaque white on its head and half of the body.. after talking to someone at the pet store where i know they raise koi.. he told me that maybe i had an amonia problem or i shocked the small fish by not paying attention to the water temp when i was changing water.. and suggested i use salt in the tank.. i wanted something A lil bitt quicker to work so that i would be able to save some of the fish, and he recommended some kind of anti bacterial tablets and melafix.. i went for melafix and well it did save my fish.. but now some of them are always at the very top of the water and when i add the medicine they seem to go crazy and look very stressed for about an hour or two

oh and the fry.. idk their maybe from july or aug.. i was surprised i found them in the pond because most of the time.. the bigger fish always eat them.. n these ones are neat looking too, i jsut hope they will live :(

oh and the fungus i was talking about..looks like a opaque type of velvet all over the fish.. its getting a little bit clearer but the fish hand out at the very top of the water.. and today when i woke up i thought it dyed because it wasnt even really swimming.. as soon as i turned on the lights it seemed to swim about a little bit.. but the poor fish looks exhausted. someone plzzzzz help!!

These fry are very young. In fact, this could be just the normal "die-off" stage for them. At certain stages some fry will just die for no reason. Their bodies just can't support them and they die. Unfortunately this is just the way it works. :( Other times, their immune systems are not fully (correctly) developed and they catch a disease and stand no chance. Over crowding will only heighten this problem. :( If you can, get separate tanks/tubs/rubbermaids Hopefully we can keep your fry.

I think the best thing for them right now will be clean water and salt. I am surprised you didn't try salt first, it actually is one of the quickest things to work with carp.

Start the salt at 1 teaspoon per gallon, 12 hours later, add another teaspoon per gallon (total 2 teaspoons per gallon) then 12 hours later (24 hours from the first addition) add ANOTHER teaspoon per gallon for a grand total of 3 teaspoons per gallon. Remember that salt does not evaporate out of your tank, so if you top-off due to evaporation, DO NOT add any salt to the new water. HOWEVER, when you change water, you are also taking out salt. So be sure to add the right amount of salt to the new water (If you do a 5gallon water change that would be 15tsp once you are 24hrs or more into the salt treatment).

I would stop the melafix for now and keep your tank very well aerated. There should not be any water on the surface that is not moving.

(Sorry it took so long to get back to you, I have been really busy with school and rehearsals lately :) )
