Wildheart2896 created the topic: I think my Oscar has Fin Rot --- Answered

This is my first post here and my first Oscar so bare with me please. I've had my Oscar for almost a year now with the tank and filter going for a while before that. His never really had a problem before but a couple weeks ago he developed a white stripe halfway down his dorsal fin and along the edge of his tail. I was informed that it was a sign of the beginnings of fin rot. I have done 50% water changes twice a week for three weeks but no improvement and it hasn't worsened. Besides the white colour his fins look fine no ragged pieces or chunks missing. His eating fine and swimming around like he normally does, acting totally normal. I was advised by the pet shop to treat it with Tri sulfa for fin rot and his had his first dose and is due again tonight. Unfortunately it doesn't say how long i should continue the treatment or if water changes are needed. I was planning on doing a 25% water change tonight then adding the meds to the new lot of water, conditioned and everything as well. The temp of the water is 26 degrees celsius but i was wondering if turning it up to 28 would help any. Water has been fine but will check it again after water changes.

Any help is appreciated.

\welcome to the community.

without the picture, it will be difficult to give good evaluation....
transparent edges on the fins and tail may also mans "new membrane"
another sign of growing up.

fin rot always shows splintered edges, and fish should be breathing heavy...

Hello and welcome to OFL. Dont medicate the tank. As DRACO stated, it sounds like the sign of a healthy, still growing Oscar. Pics would be nice, and also, what size is the tank? What kind and size of filter(s)? I would be wary of that pet shop prescribing strong meds on the description you gave. Sounds like they got the sale, all good for them. On this site we have only your enjoyment of the hobby as our interest, not your money. Yes to changing water, thats the major key to healthy Oscar.


I may not be the Boss, but I'm ALWAYS right!

Darn it.....I already put a second dose of meds in, should i just do a large water change and replace the carbon in the filters to try and remove most of the meds from the water? Will the meds hurt him if he isn't sick? I can get pics today of him but i'm not sure how to post them yet. Tank size is 3 foot it hold 160L. I currently have 2 filters going as i bought a new better one but am waiting for the bacteria to grow more in the new one before removing the old one. Or i may end up leaving both in. One is Aquatopia Internal filter the other is Aqua One hang on filter.

Water perimeters :

Ammonia - 0
Nitrite - 0
Nitrate - 10
PH - 7.4

As i said otherwise he seems perfectly fine now ragged edges or trouble breathing, he eats fine and swims over to me when i go near the tank.

don't worry, applying med for a healthy fish will be ok,
except it is just waste of money... your water parameters is good...
running two filters will always be an added features... to make the
water good ...

i was just surprised you keep the carbon in the filter while applying med...
carbon always remove chemicals and some minerals including the med LOL!

160 lit is quite tight for one oscar... i just hope you can upgrade sooner...

Whew lol that's good i didn't think it would harm him but i'll do another water change tonight to get rid of some of the meds anyway. No i took all of the carbon out but i'll replace it now that i'm stopping medication, sorry if that was confusing lol. I'm hoping to upgrade in the future to a larger tank but at the moment can't, would a 4 foot tank be ideal since i'm only planning on having one oscar? I did snap a photo though the reflection makes it look a little strange but you can see the white stripe down his tail.Oh and he was right above the airstone so there are fuzzy bubbles in the pic. :P

the picture did not help much but the spread of fins and tail shows it is new membrane. fish with fin rots normally clamp their fins and tail... with edges of fin bones exposed at the end...

I know sorry that was the best I could get but I'm very relieved that he is just growing and not sick.
Thank you so much you've been a great help!

Remove carbon from filters and dont use ever again. It does way more harm than good.Whatever space the carbon takes up is better used by having bio media, ceramic rings etc. The recommended minimum tank size for keeping Oscar long term is a 75g with a 48x18 base. If you can go bigger by all means do so. I personally believe that really big cichlids of 14+ins and 2+lbs thrive in 6ft tanks of over 125gals. Its also easier to maintain a bigger tank, as toxins build slower in larger water volumes

Thanks for the tip i didn't know that before, the hang on filter came with both so i'll just use the ceramic rings and see if i can pick up some more. Thanks so much the information has been such a big help.
