I don't think they've been classified properly yet, hence the CW number instead of a C number (as I understand it anyway :lol: ) but I think that they're believed to be closer to Melanotaenia than aeneus.

Greetings. At the present time, the Green, Red, Orange and Gold Lasers along with the "Blacks" are all considered to be different species from C. aeneus.
this Heiko Bleher again and I wanted to add to the Corydoras thread:
1. Those who write about not using fine sand in an aquarium are not "fish" but rather "plant" people. I think still the most important in any aquarium (to be successful and correct for the fishes) is, to give the creatures who have to live in it, that what I need, what they are used to and the companions they know - recognize.
2. The theme public aquarium in São Paulo - unfortunately - has actually little to do with what it really looks like in nature. I tried for year now, to do really - nature-like authentic aquarium decoration for that habitat were I went, which I saw i nature with my own eyes and were I collected the fish species and only those I place together. In an decorated environment as I saw it, with similar (or same) rocks, gravel, sand, driftwood, plants etc. Only the fish-community which lived together and the density as seen, or researched. It is an different approach, but a very successful. Almost every tank I decorated this way, was so welcomed by the fishes placed into it, that 9 our of 10 started to spawn the same day I placed them...
Who can say that from another way of decorating and tank?
And yes, some Corydoras may live longer (and even look happy) over large gravel or rocks, but believe me it is not their environment and sooner or later they will be unhappy. Make one part with fine sand and the other with rocks if you want them, why not?
Best regards from one who has discovered many Corydoras (such as C. haraldschultzi, C. sterbai, C. xingunesis, C. araguaiaensis, C. gracilis, etc., etc.).
I was looking at the Practical Fishkeeping website and I saw a picture of a blue cory. I'm not sure if it was the lighting or if there is a genuinely blue cory out there. If there is I'd love to know what they're called because I think I might have to get a school.
I tried doing some research myself but all the "blue" cories are not actually blue.
Thank you for posting the info and pics about the authentic aquariums, Heiko! It all looks great - the fishes are bright and happy. I am afraid, however, that there are not so many of us amateurs, who are able to recreate anything close to the natural habitat... We have to try our best, I guess!
Hi i've already posted these pics on site, i can't believe I never noticed the BIG difference in the markings. The big cory someone got for me with another and said they were cory julli - so when I got more I went for julli in the fs and I'm hoping the difference in markings is cos the one with the spots is younger? Have i got 2 different sort of corys? if so what are they? :dunno:
So they're not the same? one is a false julli and one is just a julli?
The whole point of my getting more was to have a group of the same species - will it still work now cos I don't what the original 2 false jullis to be left out the group ( they seem to get along just fine and I've seen one them playing together.
Right, they're two different types. But they're close enough in markings that they will probably shoal together fine. As for breeding though, I'm not sure they will cross breed. I'm no expert. Maybe Coryologist can answer that?
Greetings. I'm no expert, either, but I can add that C. trilineatus are extremely variable, to the point where oftentimes one might think that they were most assuredly looking at two distinct species in one group of fish. Additionally, unless the collecting point of the fish is known, there is no way of knowing what you have. The exporters list the fish as C. julii and the person at the lfs is usually instructed to label the tank to match the packing list of the shipment.
That being said, you should just be sure that you have a group as large as you can comfortably house and enjoy them. The larger the group the less chance of cross-breeding, which is theoretically posssible, but extremely unlikely and not something you are likely to encounter.
Thankyou jeaninel, I could kick myself for not seeing the difference! I've got a male and female (I'm hoping) of the false jullii and unsure about the rest cos they're still young. I'm not trying to breed so it's not a problem - just as long as they're happy.
Thankyou for your response, I've got 6 now which is all my tank will hold. They appear to be ok together. Sorry for taking up the pic thread with questions.
yeah a question on corys do like live bearers of all types or will they fight a bully them...and what size groups should they be in..1 and 2 or like 5 and 6..thankyou.
Cories are very peaceful and get along with everyone. They are a schoaling fish and should be kept in groups of 6 miniimum. A lot of people only keep 2 or 3 but it really is best for them to be kept in larger groups. The larger the better!
Whoever on here told me that Pygmys love plants (probably Byron) wasn't kidding. here are three pics of a pygmy checking out a leaf near the top of the tank (!), and then just perching on it! For the longest time today I thought I had lost one, but he was hanging out on a leaf too.
These are my new peppered cories, I am considering getting sand or a softer substrate as two of them are slowly losing a barbel on one side, ket me know what you think!!
