mixing up cories

[fatboybaby]

hiya

some of you may remember i recently got rid of lots of my mistake fish that i'd bought as a beginner and i am now attempting to start again more sensibly.

i now have a:

29 gal/100 litre with
2 angels
1 hatchetfish
3 bronze cories

and a

14 gal/55 litre rekord 60 with
9 harlequin rasbora
3 guppies (1f 2m)
2 ottos

i asked for some advice on the chit chat page and got recommended that i should get 1 or 2 more ottos, and 2 female guppies to sort out the ratio for the 14 gal, and some more cories for the 29 gal - maybe 1 or 2?

so i was wondering do i have to get bronze or can i get a different type? 2 of my cories are huge and fat but one is a bit thin and small so i thought of increasing the shoal size to help him a bit.

as for water params - i've been a bit busy the last few weeks but all is in the ok area apart from nitrates which are still high - i think because of the overstocking i used to have - i should really do lots of small water changes to get this level down shouldn't i?

any comments on my proposed set up greatly appreciated!! thanks!

Just a thought: if two of your corys are big and fat and one is small and thin, then the two fatties are likely to be females and the little one a male. Males are typically about 1/2 inch-an inch shorter and quite a bit thinner than females.

Fortunately, gender ratios don't matter much with corys, as they are not aggressive even when spawning. If you do get more it might be a good idea to get another bronze (or an albino= white bronze) as they are more likely to school together.

ah i didn't realise males were smaller - that might make sense about why he seems happy and normal despite his diminutive size

"Armored Catfish enjoy being together so keep a group with at least six Cory Catfish of the same species together in the same aquarium. If you have a large aquarium, say 50 or more gallons of water, you can keep two different types of Corydoras Catfish and have fun watching each type keep its own school."

I have found that different varieties of corys will swim together if they look similar.
I have 3 different types with spots (similis, napoensis and sterbai) which will all swim together, the bronze ones sometimes swim with them but tend to stay with each other.

Hi fatboybaby

You can have the same species, but 2 different colors, and they will all be happy. Bronze corys are of the species C. aeneus, and so are they albino corys that can often be found in the lfs.

Actually, there are no corys that don't get along with each other. I have several odd ones that I haven't identified yet and they fit in nicely. I hate to see a lonely cory at the lfs, so if all their tankmates have been sold I always buy them. At least they have a happy home with lots of other corys. They never seem to mind.

As for your nitrates, why not do a water test on your tap water. It's possible that it's naturally high. If so, you will have to do extra water changes, or stock more lightly than usual.

thanks for the info all!

i will stick with the bronze aeneas then. not too sure if i would like the albino version but i'll see if they have them in my lfs next time i'm there.

i live in london so i think my nitrates are 20 to begin with, did a large change yesterday so will see how the results look over the next few weeks or so.
