knee Posted March 22, 2023 Share Posted March 22, 2023 Noticed one of my panda Cory has a white spot in the eye. The fish acts normal and does normal cory things. Just wanted to check on here and see if there’s a remedy for it. Link to comment Share on other sites More sharing options...
Biotope Biologist Posted March 22, 2023 Share Posted March 22, 2023 Fish get all the eye ailments we do! Our eyes evolved from there’s after all. Having that been said that very well could be a scratch or something healing id monitor it to see if it goes away on its own. 2 1 Link to comment Share on other sites More sharing options...
Lennie Posted March 22, 2023 Share Posted March 22, 2023 (edited) Interesting. Did some googling and I've found this @knee https://fishhistopathology.com/?p=2697 Seems like cataract do exist in fish and there are many reasons that may cause that. That would be hard to sort out which one I guess Edited March 22, 2023 by Lennie 1 1 Link to comment Share on other sites More sharing options...

Lennie Posted March 22, 2023 Share Posted March 22, 2023 Also dissolved co2 seems to play a role to increase cataract too it seems? Do you use co2 in that tank? https://www.researchgate.net/publication/272754711_Effects_of_Dissolved_Carbon_Dioxide_on_Cataract_Formation_and_Progression_in_Juvenile_Atlantic_Cod_Gadus_morhua_L https://umaine.edu/cooperative-aquaculture/investigation-of-cataracts-in-atlantic-cod/ No clue if these are any related. I just found it to be interesting and googling with you at the same time hoping to find anything useful! Link to comment Share on other sites More sharing options...

Yes fish do get cataracts, I've never seen any of the pandas with that before, but I did see it on one of my black corydoras fry (not on any of the others). I was able to clear up a bunch of it with salt + kanaplex. If you can isolate that guy, try that and see if you see any improvement after 2 full treatments. I think Colu had mentioned in my thread it could be the result of a physical trauma as well. Maybe the shipping caused an issue or something? 😞 On 3/22/2023 at 11:01 AM, Lennie said: Also dissolved co2 seems to play a role to increase cataract too it seems? They were in a tank with CO2 for a portion of their life. The newer/smaller pandas never were. It would've only been the adults and full grown ones. Black corydoras and the pandas were never in the same tank and never had the same equipment used so I don't think it's any sort of contamination, but for the sake of clarity this is what I went through. Little Riddick as she's been dubbed is doing perfectly fine, but just has some eye injury of some kind. Link to comment Share on other sites More sharing options...

The hospital tank I have has been cleaned and has been sitting empty for almost two weeks now. Did you just add kanaplex to the tank or with food? 1 Link to comment Share on other sites More sharing options...

I always feel like I'll overdose food and waste meds. I often only do bacterial meds in the water. The cory does seem to have cataracts. And needs special care. When she was in the tank she stayed in one spot and I'd target feed her. She's got her own tank now just for her. Link to comment Share on other sites More sharing options...
nabokovfan87 Posted March 22, 2023 Share Posted March 22, 2023 You can use light and shadows to detect how "blind" the fish is. Moving it along the tank or casting a shadow to see how the fish responds. Riddick basically has permanent issues and does respond but not well. Has a little trouble seeing food and likes to graze a lot as a result. Sort of scatters around everywhere nosing everything instead of being able to hunt food. She does respond a lot to vibration.

rockfisher Posted March 22, 2023 Share Posted March 22, 2023 I have a blind Cory. It does fine. It gets around finds food with no troubles. He moves slower than some others, but does fine. Not that will happen but if it does he should but ok. The only thing I do that I don’t do in other tanks is feed more small sized sinking food. 1 Link to comment Share on other sites More sharing options...

Reactor Axe Man Posted April 7, 2023 Share Posted April 7, 2023 It looks like Murphy has one in his left eye. Excuse the grainy pic, but it's a webcam grab from today resized. Does this mean he's getting an eyepatch? @Cory Link to comment Share on other sites More sharing options...
