Pajama Cardinal Breeding

[urchinkiller15]

Has anyone ever successfully breed Pajama Cardinals? I have 3 pajama's in my 65g and was wondering if there is any chance they would breed?

 

[FMarini]

yes---
they are even bred commercially. However don't expect them to be like "Banggais", in their breeding

Please do a search in this forum

How likely is it that I have a male and female in my group of 3 PJ Cardinals?

with three fish you have 8 possibilities

Only two of these give you three of the same sex, so I would say you have a 6/8 or 75% chance that you have a pair. This is assuming that PJ cardinals are a predetermined sex (like banggai) and can't change (like clowns)

Does size vary between males and females? Out of the 3, two are larger and one is smaller.

I dont think that is quite right
The ones in red are all the same, 2 males and one female, and the ones in green are all the same, 2 females and one male. Then you have the all males and all females.

That is 4 possibilities... Two of them are "good" and two are "bad". That is a 50/50 shot, or 50%.

Hi, I too am in search of breeding info on Pj's. It appears that one of mine has a mouth full of fry today.

So far this is the best info I have found:

I have also found out the the males are a bit larger and their jaws are slightly more rounded.

Good luck!

You are right in saying that they are all the same, you are wrong in your interpretation of how statistics work. camlov2 was correct in saying that you have a 75% chance rather than a 50% chance.

A quick explanation of why this is the case: You have three fish, each with a 50% chance of being either sex. As a collective group there are four possibilities, but because each fish has their own individual chance of being either gender, you have to consider each fish individually. Treat the first column of 'm's and 'f's as fish 1, the second as fish 2 and the third as fish 3. If you look at it that way, considering the fact that each fish has their own individual chance to be either gender, there are 8 possible combinations.

Or in simpler terms,that 3 fishes belong to the same sex is like throwing a coin 3 times and get the same side up.

 

[joeybemate]

Yeah exactly

 

[joeybemate]

Three coins would have the same explanation I gave for the fish, so with the same logic there are four different sort of combinations but 8 possibilities
