Where are my tubercles??
« on: March 11, 2012, 05:29:56 PM »

This is the situation thus far. Two of my 55s have heaters in them (there were parasite issues a few weeks ago) Out of those ten fish four are over a year old, one has tubercles (Hazel). Now in the main tank all the fish are 1-3 years old. Rowan is supposed to be male- the breeder told me so. But no tubercles! I thought it was because the tank is not heated and hangs around 72 degrees but why then am I "swimming" in eggs?? If it's warm enough to lay eggs shouldn't the males be showing? How very unlikely that they are all female! Two orandas are thin and have concave vents- so I thought I had two males. Now I just don't know...My dreams of fry are slipping away.

Watch for the behavior of the fish. Males tend to be doing the chasing when they are in breeding condition.

As a general rule,  the male goldfish will show the tubercles ( males can get them at 3-4 months old but can very depending on the individual goldfish) .
Male fish will get the tubercles when they are in breeding condition, which you can sometime see on the leading edge of the pectoral fins also in addition to seeing them on the gill cover.The males if they are old enough should have little white bumps in a line on the first ray of the pectoral fins . Checking the tubercles on the pectoral fins is a better way to tell if a fish is a male or female , since some orandas and ranchus with hood development tend not get tubercles on the gill cover or very few.

check out the white dots on the pectoral fin of this male

If the fish is still very young, you can check the front ray on the pectoral fin. If the ray is very thick it's most likely a male.


Another way to tell which gender they is to pick them up with your hand. The female will have a belly that  will feel soft and jelly like if she is in breeding condition  while the male will have a stiffer belly.

female- narrow protruding slightly out(more so when spawning)

male - wide and normal or slightly caving inward (concave).

Nabi thank you! I have been carefully inspecting the gill covers not the fins. It does appear there are tubercles on one guy's fins. And he is very slim and very "enthusiastic" in harrassing the girls.

Did they lay eggs fantailer?
I was lucky enough to watch my two young fantails spawn this morning! I decided with the orandas to seperate the male I want to breed from the best female so it wont happen naturally. I guess I'll give it a go on Sunday and see what happens.

Then how do you know for sure they are girls and not just undeveloped males? I only have 4 that have shown to be male but I seriously doubt that means 15 are female. I only know for sure that two are female- the rest are still undecided.
