corydoras hastatus vs corydoras pygmaeus
 
I'm posting this in the hope that coryologist will be able to help, but anyone who knows something would be very much appreciated.

I have had a 15g lying about for some time now and am eventually going to set it up.

I love cories and want to make it a cory only tank and hope that they will breed.

I don't know if I want normal siized cories, perhaps sterbai, or good old plain bronze/albino cories, or whether I want to go with a smaller species so I can have a larger group of them.

So if I go for the smaller species I can't decide between corydoras hastatus or corydoras pygmaeus. They're both ridiculously cute, so that's not a factor. I mainly would like to know about the hardiness of each type, and the ease of breeding each type. If anyone can give me any info it would be really appreciated.

Also, in a 15g how many would be a good number? If I go with normal sized cories I was thinking 6-8, and if I go with one of the smaller species I'm not really sure how many at all I should add. It will be a planted tank and will be only cories inhabiting the tank.

Thanks.

Hi. I find both species very easy to maintain. I think the C. pygmaeus may be a bit easier to spawn.

I don't know if your 15 G is U.S. or Imp. - but in a 15 USG tanks you can easily keep 30 to 40 fish.

Good luck. - Frank

Thanks for the reply Frank. It's 15 Brittish Gallons which is about 18 American gallons. I don't want to overstock so would probably go with 30 pygmys if I decide on them.

Sorry for all the questions, but do you find the pygmys any less hardy/difficult to spawn than the regular sized cories? If I went with regular I would choose either Sterbai, Aeneus or Paleatus. I know that these species are pretty hardy and I have had luck aready spawning the Aeneus variety.

Thanks again for your help.

Just come across another dwarf species that is in stock: Corydoras Habrosus. These seem a bit prettier than the other 2 though I have neevr heard of them until now.

That will work.

All of my Corys spawn with little intervention from me. Good conditioning and water changes are usually enough.

They C. sterbai are a bit more difficult, but your mileage may vary.

Hi. I think they are the largest of the pygmy Corys. I beieve you will find the C. hastatus to be the most entertaining, but it all comes down to personal choice. - Frank

Wow! I'm beginning to envy Frank and Julie with the dwarf species lot they get.:( I've been checking from time to time my two lfs for corydoras stocks.:roll: I'll be lucky if one cory doesn't cost me a hand and a limb depending on the Law of Supply and Demand.:shock:

cories are easy to find here... but thats just it. they are just cories. no family name, nothing.. just corydoras catfish lol i made some kid at one of my LFS's write in "peppered" on the tag for his tank of peppereds just labled as cory cats.

all i ever see here is peppered and false julii cories :(

I know that but the fact that only a few species are available is really irritating me.

False julii is possibly trilineatus. I've known both species to be confused in several forums.

Thanks guys for the replies. I still haven't made up my mind but have narrowed it down to either a dwarf species, or sterbai. If I choose sterbai I MAY put a betta in there as well, but not if I choose the dwarfs, I'd be too worried he's eat the dwarfs.
