corys going nuts
×
Hi,
John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.
I wish to thank John for his hard work in keeping the forum going.
With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.
I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.
If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.
I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.
I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.
Thank you
Darragh Sherwin

wasnt really sure what topic to put this under but here it goes,have seven sterbai corys two adults and five juvies,and noticed them starting to really move around the tank just before sunset,more than usual! they just seemed to be getting worse by the min,then i hear this awfull racket outside and it raining cats and dogs,really didnt see it coming tbh,but it dawned on me that the corys might have seen it coming? would this have an effect on them or am i reading into things a bit to much?

Corydoras usually behave erratically when there is a change in Atmospheric pressure which is a precursor to breeding, nothing to worry about.

If it was frantically chasing each other around the tank, nudging each other etc, then its a pre-cursor to mating behaviour. Like many fresh water fish species from tropical areas, Corys typically spawn at the start of the rainy season. ITs why for successful breeding, its required to lower the nitrate levels by frequent water changes, it mimics the natural environment during rainy season, by no means the only water paramenter the changes. The pressure changes before this evenings downpour would have indeed as you suspected, been a trigger for the fish.
If you google the breeding behaviour of corys, you will find all the info you want on the subject.
Cheers,
Bill.

Kev and Bill have summed it up pretty well, the change in pressure would be far more noticeable to fish than to us mere mortals.
The 'trigger' can be partially replicated by doing a quite large water change - but using cooler water. This is a ploy used by many Corydoras breeders with the change coming well after a 'normal' water change would have been done - ie if you normally do this weekly then leave the change to a fortnight.
This will often work - like magic.

Any one with corys out there?
If so are yours acting stranger than normal?
All mine are going nuts at the minute
Would love to know if there's any doing the same?
