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

URGENT: cory sterbai eggs: what to do next

More
25 Nov 2010 23:15 #1 by joey (joe watson)
just got home and seen wee eggs in my planted tank. all that is left are the cory sterbai so finally these buggers have spawned! dunno if i did anything to trigger this, only a 25% change yesterday and a heavy dose of ferts for the plants

anywho, i removed what i could from the glass and have them in a wee bowl. what the hell should i do with them next?! i have a shrimp tank i could put them in but there are 1 or 2 assasin snails hiding in there, would they eat the eggs?

help i need to do something with them i really would love to raise some of these!

For the moment you could put them in a hatchery, if you dont have one put them in a tub floated in a tank.
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.

So you didn't get to experience watching them spawn. Fascinating stuff.

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.

sorry - just posted this in the catfish board but only saw this board now and it prob fits better here....any thoughts:

hi....got some cory eggs a few days ago, put them in the breeding box i use for guppies...they hatched today....some fry went missing and i just saw one slipping out into the main tank so thats where they have gone!!!....these guys are so small!!! Dont have a spare tank so any other ideas on how to keep these small fry apart?

get a breeding net, its only 5 or 10 euro max, and its very very fine mesh nothing bigger than a brine shrimp egg will get thru. had one fry out of the original spawn but he went missing. they have spawned twice since, one today (again missed all due to work) and one last week. i now have 5 fry from last week and 12 eggs tonight (i must have been too late to get more) and what i did this time was put some protozin anti fungus in the water, none of the eggs from last week got fungus (at least 4 from the 1st batch did) and i got 5 fry surviving, i hope i get another couple from tonights eggs, and i changed another 10% water so maybe i'll have more eggs in a few days! randy buggers get way more than me...

Joey,
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.

was by pure fluke, i thought they never would as my water is a bit hard and pH above neutral, and temp is fairly high for most cory breeding. chuffed as fudge tho! i probably wont get the chance to take the eggs out straight away anyhow, i am not home til 11pm most days so miss the "magic" ;)
cant wait for these guys to get big, am bouncing between selling or keeping....
need to test water to see is it safe to do a few water changes a week for these and the leleupi but just cant be arsed i'm stuck to the sofa and scrubs and the laptop are on

Sterbai are one of the better able to cope with warmer temperatures - many people have them as first choice as Discus tankmates - I'm planning to get some to keep in with the Zebras and the lovely little Neons I got from a lad at the Blue Ball.
They are pretty pH tolerant, but when you're able to it would be good to get it down somewhat.

yeah they are hardy guys alright i put one poor bugger through a fair bit when i was starting off in the hobby, but he/she (still not able to sex these, i barely get time to see are they still alive) is still here!
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

I'm no expert, but if you do go down the CO2 route this will help reduce and maintain a lower pH for you - cue Ian or Platty for confirmation. But it's still a good idea to check both rocks and gravel too.

the blonde hitler got some "pretty" pebbles and stones she liked and wanted for the tank and i didn't think they would affect the water so when i strip it down i'm sifting the gravel into various sizes, and will test the small medium and large stones with strong vinegar (unless someone knows where i can get strong acid) and probably sell half of it and get some peat for a bedding
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?

I'm a little uncertain about water chemistry (or chemystery as I call it) so it will be better for someone with better knowledge of these things to step in here.

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

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

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.

wow someone concentrated far more then me in class!
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 :)). I had an added bonus of the UK taxpayer paying out lots of money for my chemistry education.....so a good reason to concentrate.

Have you managed to watch the complete spawning cycle yet?

not a chance with my work hours at the mo, and they haven't spawned again for a while despite the live food and cold water changes. will try to get a big water change done before my next day off (xmas eve) and try to catch their behaviour, even hav the camera ready to try to get a vid
