If I were you, I would change the gravel to sand, if you're planning to keep Corydoras. Also Ancistrus and L-cats like to have soft sand underneath their bellies, but to Corys I regard it as a must-have. I would never keep Corydoras on gravel. Fine sand is also more pleasing to look at. All fish thr...

I think my favorite must be Corydoras adolfoi , the very first one I bred. I'd only had them for 3 weeks, wild caught fish and everything, when I suddenly found eggs on the glass one day. I think I must declare them as my first true love! ♥ And you never forget your first love, do you? :-) After the...

I've had several Corys without barbels, for different reasons. A Corydoras without it's barbels will survive , but in my opinion they seem to be a bit sad and unhappy. They're not as happy as their mates with barbels. It's totally understandable, since the barbels are their contact with the surround...

I don't think that is correct, they don't need to be 2 or 3 years old to produce viable eggs or fry. I've had 8½ months old Corydoras panda who spawned and the eggs hatched and fry appeared. I've had other youngsters from my own breeding as well, that produce viable eggs at a much younger age than 2...

Any ideas please?? What is the water parameters? Ph, gh and so on. It might be that your water is to hard for the eggs to hatch. I've raised lots of Metae corys, they just fix that themselves, with lots of youngsters growing up in the tank with the adults. Lots of java moss in my tanks gives the sm...

I've never tried banana leaves in one of my tanks, but I regularly use both catappa leaves (sea almond) and lots of oak leaves. Thanks to eBay, I've found a supplier of Catappa leaves from Asia, and I usually put one or two (they are large, although I order "small" size)catappa leaf in eac...

Corydoras usually does fine with only one eye, since they are evolved to manage murky waters with not much sight in the wild. I've had a couple of one-eyed Corydoras during my time, and they never showed any signs of ill comfort or problems. Healthy and fine, just as able to find food like all the o...

Birger...wake up There's a huge difference. I'm not keeping anything in a tank that isn't cleaned and scrubbed thoroughly in hot water every day. That effectively removes any harmful the bacteria or prevents it from building up.

Oh, seeing Corys in such condition breaks my Cory-loving heart =(( . You really should not keep your Corydoras in a bare bottom tank. Please get some sand in there, so the poor little fish can grow their barbels back...:-( Bare glass bottoms will in many cases develop a bacteria film on the glass, w...

Corygal wrote:I fed them peas because of the swim bladder problems - to break up any impaction/constipation. They do not form part of their normal diet.

Wonder who came up with that idea to begin with...? Do you remember where you read it the first time or...?

Is there anyone here that can translate the posts in the link above? Looks like something like Polish language to me?
It would be interesting to know more about how that cross-species breeding came to be. Did the owner keep only one of each sp. or what?

Why are you feeding Corydoras vegetables like peas?? They're not herbivore. They are more omnivore to carnivore, and prefer a diet of insects like bloodworms and tablets like Tetra TabiMin.
Their small size is because they are one of the dwarf species of Corydoras, like Mats says.

I think maybe you will have to wait a while for the fry to develop their adult markings. Around 6-7 weeks, I guess, they will reveal their true identity. Before that age, there isn't many Corydoras fry that we're able to identify for sure. Most of them, with a few exceptions, will all look pretty mu...

... And my fish had spawned while I was out of town and unfortunetly the fish ate all the eggs If 3 single, different Corydoras sp. is what you have in your tank really spawned, I would say it was the best solution that they ate their eggs! There is no reason why you should raise mixed-breed fry, o...

I'm not sure I get what you're asking correctly. Are you thinking about buying only ONE single Corydoras melini? Or a whole group of them? Since you haven't mentioned anything about thank size or how many fish you've already got in there, it's a little bit difficult to answer. Buying a group would b...

OK, I will start a new thread under another sub forum

Something slightly different from a normal water change was done, yes. Not much, but it did the trick. I just added peat in the water barrel, then I removed it and filtered away the particles. Then I used that water to make a normal weekly water change. The ph was 7 at the time of spawning, which to...

Hello I have bred a sp. of Corydoras where the info on the sp. profile says "Breeding; Unreported". Profile: http://www.planetcatfish.com/catelog/species.php?species_id=471 At the moment I have about 70 juveniles of C. condiscipulus, and they are 4 months old (hatched in April). I can add ...

Mark; In Norway the tap water in general is very soft, yes (both kh and gh) Birger and I have about the same water measurements although we live a couple of hours drive by car from eachother. The softness of the tapwater makes ideal conditions for most of the South American fish species :-) 11069_07...

PS!
There is no walnut trees growing wild in our cold climate The winters are too cold for them.

But we have similar methods to prevent eggs getting fungus;
oak leaves or alder cone extract is a good substitute.

Hello Birger It was in 2007 they were born, and I think we did the swap the next year, Birger. Or was it later that same year? Anyway, your fish was born in february 2007 (according to my notes) So your group is a little bit over 3 years old now. I remember it well because you got my first batch of ...

I got one with a brown spot on the head in my latest batch of L144. It's a flaw, and not something one should breed later on. I gave the fish to a fellow aquarist who promised not to breed it, and keep the fish as the only Ancistrus in one of his tanks. The fish was born with the spot on the head. U...

The water parameters at the time of spawning this year was about the same as last year. We have fairly soft tap water in Norway. Ph 6.8 Gh 1 - 2 Kh 2 Temperature 26°C The spawning took place after a period of 3 weeks were I did cool water changes every other or every third day. The water temperature...

I noticed today on C140's fish profile here on Planet Catfish, that under "Breeding" it said "Unreported". Is it possible for me to ask for a change there, send an email to someone for instance, and change the text to "Has been bred under aquarium conditions" instead? I...

Second picture

It's been a while since last update, but all youngsters are doing well and I haven't lost a single one since my last post in this thread :D They have been counted, and there's 175 of them...guess I will be supplying this species to the whole of Scandinavia! :lol: Here's a few of them at feeding time...

3 weeks old now and doing fine.
Really cute too!

The C140 group is spawning again today! :D First time since last summer! :-) They started around 09.30 (norwegian time, 08.30 english time) this morning, and they're still spawning "as we speak" :-) And the female(s) sure carry a lot of eggs in each load, I can tell you that! At one point,...

My Corydoras caudimaculatus group spawn on a regular basis, but since they're in a community tank with lots of plants I've never taken on the task to pick out the eggs. But they sure are a pretty specie! :D Here's a pair of them in the classic Corydoras T-position :) 4 nov07 T posisjon C caudimacula...

There seems to be several Corydoras species which are problematic in either obtaining a decent hatch rate or as in your experience you get many larvae but there is a high mortality rate before they under go final metamorphosis. For me these include C. duplicareous and C-121 which share some resembl...
