Danny LeVeck Posted January 16, 2021 Share Posted January 16, 2021 I got 6 corys on Sunday. They’re all great, eating, parameters good. However, one of them flashes. Should I be concerned? If so, what should I do? Link to comment Share on other sites More sharing options...
FrozenFins Posted January 16, 2021 Share Posted January 16, 2021 What do you mean by "flashing". Are they swimming up and down the decor and the glass? The best way to know is if you send us a video. To do this you will have to post it youtube (or another social media) and then send us the link Link to comment Share on other sites More sharing options...

He did it only once tonight while I was feeding him, so I didn’t catch it on video. 1 Link to comment Share on other sites More sharing options...

CorydorasEthan Posted January 22, 2021 Share Posted January 22, 2021 Only my Corydoras aeneus do this in my tank. Also some of my guppies and siamese algae eaters do it. The Corydoras paleatus, Corydoras pygmaeus and the pearl gourami in the tank do not though. I don't know why they do it, but it's been a long time since they started and they have had no problems that I can see. They behave just fine and are perfectly healthy. So I would not worry too much about it. Of course, I am not an expert, so I will leave it up to the more experienced hobbists to sort this one out. Hope this helps. (If I am wrong about anything, please correct me) 1 Link to comment Share on other sites More sharing options...
