Corydoras Adolfoi

[NEONCORY]

Hi All,

I am wondering if anyone here have been kept C. Adolfoi successfully and possibly bred them.

Since I am considering getting some of them. I was at the local fish store yesterday and saw pretty nice looking ones. They are not quite adult yet but pretty close, probably about 1 1/2" SL and healthy looking. And top of that, they had the lowest price I ever see around here. They usually have price tag of $19.99. Once in a while $14.99 but it was $9.99 yesterday.

I hear/read that their frys are tough to raise. But how tough is it really, I wonder.

So I appreciate if anyone have some first hand experience with them that you can share.

Hello,

I have 7 adolfoi that I am trying to breed for over a year, now.
They are alone in a 50ltr tank with daily water changes of 20%. Temp 26º, pH 6.5 and low conductivity. Not a single egg. I guess they are very hard to breed.
In Portugal they are extremly rare in stores, I maneged to get some in specific imports for 10? each. So, for my standard, $9.99 is a very good price.

Sorry, this is not much of an help, but is my experience?

They need fairly soft water and a lower pH than most corys. It would probably be beneficial to add some blackwater extract to the water (and to have lots of bogwood as decor).

Hi Gogool,

A year huh. What size are they? And what the sex ratio?
And yes, I do believe this is a good price. Especially around here.
No problem. It is always the case some corys are easy to some aquarist and give troubles to other. But they are one of the pretty cory. And I'm sure you like them. Hopefully, they will spawn for you sometime in near future. They usually do when you least expected.
I'll let you all know when I get them.(most likely next Tuesday)

C. adolfoi are not particularly difficult to breed but as you rightly say they are extremely difficult to raise. The fry actually need to be swimming if food soup, because they just do not search for it. One trick is to put the C. adolfoi fry with the fry of another easy to raise species and what happens is that the C. adolfoi fry seem to learn from the other fry and start to pick at the food particles. It works for me.

Thanks for the tips, Coryman,

It is still further down the road as I have not even get them yet. But I am going back to the store on Tuesday and get some group since they looked good. And of course the good price also help me decide.
And judging from their looks, they probably need few months of growing/maturing to do. And then, hopefully I can get some eggs from them.
Also I hope I have some frys from other corys to raise with them.

But now, I need to go get me some of the pretty corys. And see how it goes.

Anyway, thanks again for tip. I'm sure it can be useful someday. Hopefully not too far down the road.

Hi. A beautiful group of these which I recently acquired, spawned for the first time, today. Only 18 eggs, but they were perfect. The albino C. aeneus were spawning in the same tank and I guess it put them in the mood. We'll see how the eggs fair. - Frank

[NEONCORY]

Hi nice to hear from you, Coryologist. Especially after the misunderstanding I make you go through.

Anyway, I should pick some up in few days.
I also decide to add few more group of Corys today.
I figure I am spending enough time as it is. What the other few more tanks, I thought. I know it is beyound MTS but I just love to see the eggs hatch and the frys grow. And mail ordered some CW009, Albino Sterbai and Similis. So I am most likely look for some good tips from someone who had them before. hint hint
Especially CW009, it seems I can even find the information about their prefered water parameter.

Unlike you, no new eggs for me but I got 190 or so eggs from Melanotanias(these guys always make me wonder "is it so tough to survive in the wild that you have to lay so many eggs? Especially I did find 180 or so eggs day before . And I only have 2F and 3M. But I must admit, they know how to group eggs in neat manner. ) and 60 or so from Sterbais.

P.S. It seems you need to update your inventory list and change some name to BOLD face. Especially the name you waited for 5 years.

See you around.

[kim m]

I've bred the CW009 last year.

They spawned 3 times in a tank with water of pH around 7, TDS around 100 and temperature of 24 degrees celcius as far as I remember...I put a spawning log on Corydorasworld anyway.

The 2 spawning came within a couple of weeks and then the fish stopped and now the biggest female has died, so I'm looking forward to see if they will start again in the autumn.

Hi. Ancient history and not a problem.

And mail ordered some CW009, Albino Sterbai and Similis. So I am most likely look for some good tips from someone who had them before.

Well, I have had only one accidental spawning of CW009, so I can only relate my average tank parameters, which are pH = 6.8 - 7.2, medium hardness and average temp at the time = 68º F. I have 4 groups of 8 fish each, and although very healthy and active, no action from any of them.

The C. simlis were one of my steadiest spawning groups, until I lost a male and then the group stopped for around 4 months. Finally, I introduced 2 F1 males into the group and within a month they were back up to their old routine, spawning like clock work.

P.S. It seems you need to update your inventory list and change some name to BOLD face. Especially the name you waited for 5 years.

Well, the albino Sterbai did not hatch-out, but I did get around 20 viable looking eggs on Saturday. I hope they make it. - Frank

Hi kim m,

I knew I can count on you popping in. You always have some experience with the specie of Cory I need help with.

I've bred the CW009 last year.

Hopefully I can say that before next year.(spawning this year)

They spawned 3 times in a tank with water of pH around 7, TDS around 100 and temperature of 24 degrees celcius as far as I remember...I put a spawning log on Corydorasworld anyway.

Darn it, I don't have access to that site YET. It seems all the available fund turn into fish.
Heck, I don't even have money to upgrade comp and get decent camera either.

The 2 spawning came within a couple of weeks and then the fish stopped and now the biggest female has died, so I'm looking forward to see if they will start again in the autumn.

Sorry to hear that. But nothing last forever. And she did leave you some offspring for you, right? That is exactly fish do. Spawn to maintain their line.
And last 2 days, once again my Melanotanias make me wonder. Is it so tought in the wild that they have to lay so many eggs? I got 180 and 190 or so eggs on Saturday, Sunday. And I only have 2F and 3M. And I thought I have just about good number of frys from them from their last spawning. But obviously, the parents disagree with me.
One good thing about this is I see the similarity between the Melanotania and CW009 also Black Anuaes(Which I do not have but I suspect they are developed from Melanotania possibly. Judgeing from their elongated body shape and some similarity in their body and fin color. Then again, I am just a regular guy living among fish and do not have any scientific back ground. )
So I am hoping their spawning behavior would be similar. And give me loads of eggs. I guess I just have to wait and see. Hopefully not too long.
For now, I just have to shuffle things around and make some room for the new Corys. It willl be having like doubled number of species from right now.

Anyway, nice seeing you. And I'm sure I will ask MORE questions of them once I get them in a week or so. Catch you later.

I just realized I started the topic for Adolfoi. I am planning to go pick some up tomorrow, BTW.

Hi Coryologist,

Thanks for that. I sure DO NOT want to cut off from the one of the experienced Cory keeper/breeder. I know sometime something just have to go through the experience by yourself. But it always nice to know where you can start. Like some basic maintenance water parameter for that paticular specie. Granted most of the corys have wide range of acceptable parameter. Each cory have their prefered water parameter.
If I am not mistaken, you do have all 4 kind of Corys I am about to get. So I am sure you will be a great help for me only if you want to. And hope you do.

Oh sorry about that. But you know sometime first few spawns may not turn up good. But you know when the Sterbai start, they just keep going. If the Albino is anything like Regular(maybe not quite but), I'm sure they will give you many many more batches of eggs. And I read they can live for 15+ years. So you have 10 more years to collect eggs.

I guess I better go change some water.

I will most likely start their own topic and seek some more tips once I get them in here. They should be in pretty good shape if they are up to what I hear about the seller.

Anyway, I got go. I'll see you later.

Nice how those melanotaenia go ...unstoppable!

The CW009 lay fewer eggs, but they're big. I've had between 20 and 30 eggs in each spawning.

[NEONCORY]

Good or Bad. They sure lay many viable eggs. I have about 110 hatched at the time of this writing and another 50 or so should hatch during the day, out of 180 eggs from Saturday. And I expect same thing tomorrow with the batch from yesterday.
Probably I would stop picking those eggs after this although it is so tough not to since they place eggs so neat in a spot or 2. But I must be strong otherwise I would be over run by them. Not to mention I would like to try new Corys I am about to get.

That's good. I like big eggs. I think they have better chance of survival. Bigger eggs equal bigger frys although smaller spawn. Like Panda.
How many CW 009 do you have anyway? And sex ratio?

Oh man, this was suppose to be the thread for C.Adofoi. Which I am going to pick them up tomorrow. Hopefully they still there.

[corybreed]

C adolfoi are not particularly difficult to breed. I have bred them a number of times over the years. They lay their eggs at or near the water line. My water is soft with a temp. range of 75-78 degrees and a pH of 6.5 to 7. I personally like C. duplicareus better. I find them to be more robust and prolific.

Hi corybreed,

I don't mean to disagree with someone who had done it before. But the thing I learned from reading and tips from people, it sounds like their problem and difficulty lie at raising frys successfully and not make them spawn. Like what you said, they are not paticularly tough to breed but it can be tough to raise the frys.
I guess they rather starve than look for food for far away. Therefore, the food have to be available close proximity. And that would make it tougher to maintain the water quality. Some people even say that the frys need to be taught how to eat from other specie frys or other corys. Basically, it sounds like they need to be pumpered. TLC.
Of course, I have to get them nice group tomorrow and raise them up a bit and see if I can make them spawn. And then, I may try with more live food oriented feeding program once they become free-swimming. That is my plan and I am stick to it. Fortunately I have green water, daphinia, vinegar eels and walterworms.
So I'll see how it goes.

I had a group with 2 females and 3 males (one female has died since). I have some young fish also (offspring from my own group and some bought in Germany) that i hope to get en new breeding group out of

Hi kim m,

Are you talking about the CW009, right? I should get them next week.

I just got back from the store. And I looked closely at the store, I realized they have thicker black line than C.Adolfoi. And they are not C. Adolfoi but C.Duplicareus. Although it is marked C.Adolfoi on the glass of tank. Then again, I notice there is one lonely C.Arcuatus in another tank and the girl didn't know what and how much. So she went to grub the owner and he told me that he thinks it is a C.Matae. I didn't argue since I know they charge $7.99 for skunk but he said $5.99 for the Matae. So I picked him(I am hoping since I have 2 females which I got for free since another aquarium society don't want them anymore. And they have been frisky) up. Anyway, the point is he may not know as much as me. I am not saying I know a lot but I know something about Corys.
But I already decided to pick them up anyway, so I did. Especially, I knew they have 15% off for fresh water fish on Tuesday. So I told the fish scooping girl that I would take them 4 if you have 4. If you have 5, I'll take 5. If you have 6, I guess I'll take 6. Anyway, they had 5 and that is just the number I wanted. Since I just hate to leave 1 or 2 in the tank. And it seems every time I buy 6, one die on me. So 5 is good number for me, it seems.

Anyway, they are floating in the bag at the top of the quarantine tank at the moment. I guess I have to re-research about them again.
