Sexing Crenicichla compressiceps

[ingoberlin]

Hi,

I know allready the different threads in this forum but i'm not sure about sexing so far. The statements oscillate between almost not possible and stripes at the unpaired fins and a thick belly. Are there different local forms because at the most published photos the differences are very clear.
As i want to buy more to make coupling possible, i want to be sure about sexing of my two to get not 2 males. This is, i think, in a 63 g tank impossible.
My both (7 and 9 cm/ 2,75 and 3,5 inch) have stripes at the fins, but the smaller one only fainted at the tail fin and none at the other unpaired. The bigger one has very explict and drawn through stripes (it's not very clear to see at the photos). The smaller one is inferior, so the difference could be because of this, too. Both have a round belly, but it could be because of feeding, too. Are there females with explict stripings, too?
Bigger one:

I eliminated "th" = thumbail. :wink:

It is very difficult my to know sex, to only I can say you that the mature females have the belly more pronouncing.

Males have stripes on their anal fin. Females do not.

Yup, you beat me to saying that aquatico.

Hi,

thank for the answers. I asked because it is often said that it is difficult to distinguish sexes, expecially at this forum. So i wasn`t sure to have male and female, although i orientated myself at this forum and the aqualog pictures when I bought them. My bigger one, where i thought he is male has very clear stripping. But he has a round belly, too.
Do you have any tips to "help" them by pairing. The only breeding report i know is in danish. I have only this two ones and it is difficult to get more for me to give the male one more possibilities. But i try.

Greetings,
Ingo

C. compressiceps is one of the more difficult dwarf pikes to spawn. You just have to wait until they feel like breeding.
