Cory Questionz

[Animal Lover 2000]

i have 1 emerald cory and 1 peppered cory and the emerald one tries to get to the underside of the peppeerde
could they be breeding
can i tell the gender differences
im getting 2 more cories soon

female cories are normally larger in size and have much more rounded bellies, whereas the males are flat-bellied. Cories mate by doing a "T-position". Look around the cory forum some more, I've learned a ton and congrats on the new cories

now the smaller emerald tries to chase and get in front of the bigger peppered but there bellies are both flat and im getting the cories soon not yet

Corys need to be with their own kind.
If you have the space I'd get another few of each species, interbreeding is not good for the species

 

[Animal Lover 2000]

okay
why not

Well, there are many reasons why hybridising is bad.

First of all, and the main reason, is that if the hybrids get out into the trade, and people don't know they are hybrids, they could be bred with pure strain fish. If that continues, there is a very real possibility that the pure breed could be lost.

Just look at what's happened with Endlers and guppies. There are now no pure Endler's in the aquarium trade. Imagine if something happened to them in the wild (pollution, or drought, for instance), if we didn't have dedicated people keeping pure Endlers, then they would be lost, forever; no more Endlers...they'd be extinct.

There's similar situation going on with synodontis catfish and Malawi cichlids.

As well as a species being lost, which is a sad, sad thing in itself, there's always the possibility that those fish could be useful to us; for pest control, or medicine perhaps. Think of how valuable the zebra danio has become in scientific research into heart disease, and things like that.

I know people will say, "oh, I won't sell or give any away", or "I'll always tell people they're hybrids", but what about those people; they might not be as scrupulously honest as you. Or (horrible thought) you might die in an accident and your family give your fish away. Imagine if they gave them to an aquarium or breeder and they didn't know those fish were hybrids.

I know it sounds over the top, and scaremongering, but these things are a very real possibility.

Now then , when you say emerald cory "Animal Lover 2000" is it a cory or a Brochis splenden .
I have kept both Brochis and corys in the same Tanks for years and they have never cross breed at all , ( i do not think they can ) but they some times swim together . Some one may be able to tell us if they can inter breed , but i doubt they can as they are a different specie altogether .. You never know ? do you ... Can they anyone ? ....

 

[fluttermoth]

No, Brochis species can't interbreed with Corydoras.

 

[wat100]

There you go . Nice one ..

 

[Animal Lover 2000]

wiat so your saying they cant have eggs they look the same execpt for color

 

[wat100]

Well you need to look at the dorsal fins , most Corys have 7 rays on the dorsal fin and Brochis have 10 - 12 rays on the dorsal fin .

 

[wat100]

Also Female Corys can act like Males !
If there are only two Females in the tank one can act like a Male and the other one can lay eggs , but there is nothing in them they are blanks . Odd or what ? ..

 

[fluttermoth]

Lots of fish species do that; nearly all catfish and cichlids will. The amount of eggs two female oscars can produce is ridiculous!
