To those whom may help,

i have five oscars in a 180 us gal. aquarium. About a week ago I removed a pleco due to it injuring my oscars. It was moved to another established aquarium and died days after. Now my oscars are showing signs of illness that i havent yet pin pointed. At first they had stringy something or others on their pectoral fins with bubbles on them. I started with a large water change and treated them with copper safe. The bubbly stringy stuff went away. Now a couple have strigy things trailing from their dorsal fins. I immediatley thought it was some sort of parasite. Superficial wounds that normally heal quickly arent and have a cottony look to the area around wounds. I changed water again and treated with parasite clear this morning. I am going to give them a day or two and see what happens. My levels are nitrate 0 nitrite0 ammonia 0 and a ph of 6.8. If anyone has any suggestions they woould be a help. Also they seem to have lost their appetite, which was my first indication of a problem.


Thanks

Casey

okay, the first thing we must address is the fact that your tank is not big enough for five Oscars. The tank is big enough for two Oscars. a 180 US gallon tank is equivalent to 125 US gallons, am I correct in saying your tank is around 6 x 2 x 2? Or dimensions similar? I'm sorta surprised that your nitrate level is so low, I have two Oscars in a 125 gallon tank and there's no way my nitrate is ever that low, not even after four days following a water change. What water test Kit do you use?

As for some suggestions, I think that it's probably a good idea to wait a couple of days and see what happens. I assume that you have used a water conditioner when you are doing the water changes?

What kind of filtration system are you using? Have you noticed the fish breathing heavily at all?

if the wounds is something like craters, then you have HITH; if shallow and cottony, fungi infection.

Please check the reading.... for an established tank, it is impossible to attain 0 nitrate.

since you have done large water change, i will suggest you raised the temp to 80 deg F, ripple the discharge point of the filter ( or add air stone), and add pure salt (1 tbs/25 gal) to enhance oxygenation.

Hey guys thanks for the info, my water readings were off, I must have misread or just operator error. I gave the fish a day and they are showing signs of recovery. Their personalities are back but i am going to give them a little more time but this seem to be getting substantially better. Thanks for all the info, as for a 180 being equivalent to a 125 its not its 55 gallons larger, sorry for being a smartass, yall are great thanks again

nice to know your fish ar doing well.
i believe what OFL means is 180 US gal is equivalent to
125 IMP. gal.

the tank is fine i have one in a 13 g and he is fine it all comes down to filterson your problem sounds like white worm just get some treatment and they should be fine

as stated before a 180 us gallon tank is too small for 5 oscars(180 us gallons is 150 imp gallons).to house them all for life you should be looking into a tank in the 300+ gallon range. however i am pleased to hear your oscars are doing better. keep us updated on their progress.



do you seriously have an oscar in a 13 gallon tank? how big is he. and what kind of maintenace do you do on it. im sure hes not full grown since a mature oscar can easily be longer than a foot and a tank like your describing is only at best 12 inches wide.

Oh that makes sense with imperial gallons or a UK gallon, they are doing a little better gonna do another water change.

How big is the Oscar in the 13 gallon tank Dogchain?
