Is the somewhere which shows major difference between male and female whiptails? Mine are getting to a decent size but I have no idea if they are boys or girls.

If I were to put the whiptails in a tank containing only corys and 3 apple snails you reckon anyone would lay eggs?
Cories or whiptails, I'm not fussy. I want eggs.

Um, if I got eggs do I move them or just leave them?

All i know is about cory breeding.. And for that, you need to add a tray of ice ( to stimulate the rainy season) and eggs will be laid and eaten, take off the eggs with a useless card. Feed with BBS and other small foods. Share....

A tray of ice!
Wouldn't that be the equivalent of a cold shower? I thought that got you out of the mood, not in it.

A cold shower is exactly what you want, particularly for you cories (I'm not sure about the whiptails).... if your cories are in condition and inclined to breed, doing a big water change and refilling with water that is slightly cooler than the tank is one of the methods that may be used to simulate a change of season and help induce spawning. Ice cubes are likely to produce localised cold spots in the tank, I wouldn't recomend them.

Do you know what species your "whiptails" are? maybe try doing a search of the images on this site to see if you can identify them, and the relevant gender differences.

Never be afraid to try something new. Remember that a lone amateur built the Ark. A large group of professionals built the Titanic.

Depends on the species. Some loricariines are almost impossible to sex (i.e. planiloricaria and kin)

Thanks GT, I have just spend hours trying to figure out what sort of whiptails I have.
I do know they are Loricariidae Rineloricaria but anything further it could be sp(1), cf lanceolata, beni, eigenmanni or pantanal.

I'm not great at sexing loricariines, but some points to look for are highly recurved pectorals in males, as well as, of course, copious non-evertible odontode growth along the exterior edge of the rostral region. The last pic appears to be male, but the angle of the shot is one that is deceiving.

Also, it is likely eigenmanni.

On second thought, I'll take that back; the problem with this particular genus is that it is so widespread and specific boundaries are not clearly marked.

Someone on planet catfish also thought eigenmanni.
These whiptails are about a year old. I read somewhere that they aren't mature until 2-3yrs old so there is still time for them to grow shaggy growth bits if they are male.
Mine are none too shy and sit right out front at feed time.
Last night for the first time one even sat pride of place on a big broad sword leaf. He knew full well I was watching him and did not seem shy at all.
