Jaspyjasp Posted August 8 Share Posted August 8 (edited) Hello community, Just wondering if I should be concerned about these dull patches on the cory’s skin? It almost looks like it is shedding its skin. I just rescaped my tank and they have been very excited spawningthe last couple days. They seem fine otherwise, but these patches showed up a couple days ago O_o I am using Kanaplex just in case. Behavior seems normally, lots of movement, but just this strange dull patchiness. These corys spawn every 2 weeks and I do a 50% WC every week bc of the stiphodon gobies. No ammonia. Can corys get sunburn from too much light? Any thoughts @Colu?

Colu Posted August 8 Share Posted August 8 You can get these patches with columnaris or a fungal infection what I would do is keep treating with kanaplex and I would also treat with ick X just in case it's a fungal infection if your noticing them get worse after the first course of kanaplex then I would treat with a combination of kanaplex and jungal fungus clear fizz tabs containing nitrofurazone following this treatment plan @Jaspyjasp 1 Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 8 Author Share Posted August 8 THANK YOU @Colu Is it best to treat the whole tank at this point it should I QT the few who have it? Ehhhh.. Link to comment Share on other sites More sharing options...
Colu Posted August 8 Share Posted August 8 If only a couple of fish are showing symptoms I would quarantine and treat if it's spreading to multiple fish over a short period of time I would treat the main tank 1 Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 8 Author Share Posted August 8 Thanks so much @Colu I really appreciate how helpful and quick you are! I’ll try to find some QT space somewhere 😵💫 Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 25 Author Share Posted August 25 @Colu Thank you again for your help! The corys recovered for the most part. I did two rounds of jungle fizz + kanaplex, and am now treating with Ich X because there is ONR juvenile that seems to have this yellowish fuzzy patch. He seems very healthy otherwise except this residual patch. I almost wouldnt catch it except it is slightly raised. Any suggestions of what else I should do and how long should I keep the others in QT? Thank you!!! 🙏🙏🙏 Link to comment Share on other sites More sharing options...

Thank you!!! 🙏🙏🙏 Possible secondary fungal infections you also get fuzzy patches with columnaris I couldn't rule it out if all your other have recovered what I would do if you still have them in quarantine is also add some aquarium salt 1 table spoon for 3 gallons I wouldn't get above this level of salt with Cory's and keep treating with ick X for next 5 days Edited August 25 by Colu Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 25 Author Share Posted August 25 @Colu ok thank you! I’ll try that. Yes everyone js still in QT to be safe. I’ll look up more about adding salt so i know what i’m doing 😅 thank u! Link to comment Share on other sites More sharing options...

With aquarium salt you only want to add back in what you take out so if you do a 3 gallon water change put 1 table spoon of salt back in as salt is only removed though water changes Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 25 Author Share Posted August 25 @Colu Ah ok! Thank you!! It’s definitely a math thing 👀 Appreciate the tip and I’ll try it out 🙏🙏🙏 1 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted August 26 Share Posted August 26 (edited) @Jaspyjasp definitely something there, not sure what. As always some great advice from Colu. What are the other tank parameters and temp? (KH, GH, PH, etc.) Edited August 26 by nabokovfan87 Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 26 Author Share Posted August 26 @nabokovfan87they are actually in a QT tank right now. I think they were stressed because I had done a massive re-scape and had stirred up the substrate. The ammonia readings were 0 when i put them back in, but maybe something surfaces in the tank? They also spawned a couple days later. I think all of that change and spawning possibly triggered a disease, and because they spawned for a couple days touching each other - i had about 6 cory affected. Nothing else in the main tank got the weird patches, and i dosed with kanaplex to be safe. Main tank inhabitants are still going strong, just trying to get rid of the last “patch” on a juvenile cory. Im dojng a water change with more ICHX and salt per @Colu instructions now 🤞 2 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted August 28 Share Posted August 28 @Jaspyjasp It's likely something where the combo of salt + Ich-X does a lot of work for you. Hopefully good news when you report back on that. What is the GH, KH, and temp in the tank? Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 29 Author Share Posted August 29 Hey @nabokovfan87! Thanks for checking in. I think the salt and ichX is working! The patch looks like it’s receding. Im doing 3G water change everyday and re-adding 1TB salt + ichX. I think i still have a couple days to do. In my main tank, parameters: GH: 71.6 kh: 3 temp: 76.6 ammonia: 0 i have stiphodon gobies, a panda garra, and the cory in there. I do a 50% water change every 7-10 days. All bottom dwellers :)) it’s hard to get a pic of the juvenile and i have no light on this QT tank right now. i’ll keep u posted with how things go in a couple days tho. 2 Link to comment Share on other sites More sharing options...
Jaspyjasp Posted August 31 Author Share Posted August 31 @Colu@nabokovfan87 UPDATE - Corys are doing well and the little juvenile looks clear!! 🎉 Thank you guys so much for your input, engagement, and feedback 🙏❤️ I am so happy they are looking so good! I’ll do water changes gradually to take out the salt and ich. @Colu Really appreciate your getting back to me so quickly. It made such a difference being able to tackle this so efficiently and learn how to take care of sick fish. If you live in the SF Bay Area I could give you some corys 🤣THANK YOU! 🙏🙏🙏🙏🙏 1 Link to comment Share on other sites More sharing options...
