Albino corys?

[TowBoater]

Ok, I have 4 albino, 2 emerald, and 3 peppered in a 55g. 2 of my albinos have like a hump on there head and 2 don't. Is this how you sex them?

[gm72]

Not sure about that. The females are larger and wider, not sure about the head "hump". I don't notice that difference with my 3 albinos.

hi none of my corys have a head hump the males and females only differ in size

[TowBoater]

Hmm, I guess mine are just deformed.:1:

[gm72]

Might want to keep an eye on them though, hopefully it isn't a sign of serious defect.

[TowBoater]

Well they all act normal and such. All came from same place but purchased at different times.

[Drumachine09]

Hmmm. Is it possible to get a picture of it?

[Incredulous_Ed]

The usual way to sex cories of the smae age is that the females are plump. It could be just a birth defect, but I don't really know.

Adult male corys usually have tubercles (little bumps) on their heads. If your's has a lump, its possible he was injured when captured, as they go into a frenzy and run into the glass when pursured by a net.

No, it is more towards there dorsal fin, like right before it and then fades down there back. It's like they are hump backed almost.

[gm72]

Spinal deformity? Hope its not TB.

[TowBoater]

They act fine, they were purchased at different times. I will get a pic a soon as possible.
