Retirement and forum shutdown (17 Jan 2022)
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

If you have some cherry shrimp you could add them to keep them clean.
I will let someone with more experience with corys give you info on how to best care for the eggs.

Hopefully you didn't damage the eggs when you got them off the glass. But they are reasonably tough.
Have the eggs off the floor (say in a net) and little gentle current of nicely oxygenated water.
As for stimulating....the water change would have done the trick (especially if there was a bit of drop in temp during that).
Watering cans, sprinklers etc can also help stimulate breeding.
Next time, you have to be around to watch the complete spawning cycle.....it is a mix of very overt behaviour followed by some very sneeky behaviour.
A while before the female lays the eggs she will spawn with the male....the egg laying is rather secretive, but the mating with the males is an orgy of overt flirting. Look out for the very active swimming around in pairs or trios...and that gives a heads-up.
Then you'll see public mating with the male.
So after that.... half an hour, an hour....look out for the lone female sneekin off to lay the eggs
Now you've got some spawners....you'll easily recreate this.
Best wishes.

Some Corys - Sterbai included - do spawn on a 'little and often' basis while others, like Paleatus, will often get the whole lot done in one or two days in my experience.
So keep looking out for more eggs. If possible try to not collect them immediately after the eggs have been laid as the 'shells' are still very tender but harden up after a few hours.
Well done on getting the Sterbai to breed.

They are pretty pH tolerant, but when you're able to it would be good to get it down somewhat.

IMO they are the best looking cory i have seen or googled, i love the orange fins.
you never know john, i could have a fair few of these in a couple of months and will let you have first pick, i will only keep 5 if any
oh and i hope to get a lower pH when i do this big tank again, i am going to remove and test all the different stones in there as i never thought of it at the start, as something is keeping the pH up in there too

and i know the co2 drops the pH my worry is that i mess it up and bottom out the pH killing everything. i have loads of bogwood and peat pellets in the sump, but still 7.6 when its 7 out the tap. would salts affect pH?

If I get mine going, we could mix the lines.
Try get a pic up.
The females are usually bigger.

well i should know this from my chemestry a levels. i know salts in acidic/alkaline solutions act as buffers. i will stop with the tonic salt for a while and see what happens. i will also test taps after dechlorinating
Not always.
It depends on the type of salt.
Common cooking salt (sodium chloride) is a salt of strong acid and it will not contribute to the pH, but it will have an effect on the pH measurements and it will also have an effect on the dissociation of the acids or bases in the water (and that may by a secondary affect effect pH).
ie it is not a pH buffer. Is the tonic salt you plan on adding normal sodium chloride?
Salts or weak acids or weak bases will, however, not only change pH but will buffer the pH once an equilibrium is set-up.
eg salts of weak acids generally increase pH in neutral water (because salts of weak acids are alkaline); salts of weak bases will generally reduce pH.
A good buffer is a mix of the weak acid or weak base with an addition of the relevant salt of that acid/base.
Now, to the serious bit......selling your first baby sterbai?? no way. Keep them.
It's not as if you've just breed 5 million Tilapias.

Sterbai are great fish....I keep them with high-temp Discus and will low 20s fancy goldfish. Much more active than most Cory's. If I choose to have any corys then sterbai come first.

yeah its all coming back. i dont want to add too much to my water i got a riddle off kev (sound as a pound) to get the stones out and when i re-do it, it should be closer to neutral, if not slightly acidic
yeah justin we could mix the lines up, just give your ones time. i've had mine 2 years now. since the first spawn they have been at it 3 times, 5 fry off the 2nd and none off the 3rd (was 8 eggs found is all)
did big water change and threw in a couple ice cubes last night so hopefully getting some presents tonight after work

Joey, the A-level curriculum doesn't really do a good job at explaining this stuff (the leaving cert is even worst

Have you managed to watch the complete spawning cycle yet?
