Plese help me identify these cichlids

hi guys can anybody help me with these chichlids i got them from my lfs and dont know what type they are :amazed:

 

It is seldom that they are named individually..... Where-ever I see them at an LFS..... they just labelled "Malawis - R45 ea"......

 

First pic- blue and black horizontal stripes is a cyaneorhabdos maingano. Third pic yellow black horizontal stripe is auratus. Difficult to identify the juveniles. There looks to be some possible hybrids as well of caeruleus. I will not hazard a guess on the others until they are bigger.

 

6th pic, middle on the right could be Melanochromis perileucos. You even have some elongatus species in there

 

The only one in there that I do know is the yellow and black vertical lined fish..... is a Melanchromis Auratus...... and I do not think they are true Malawis.... They gou bluish-black when they age and are extremely aggressive.....

 

If I am correct, juvi auratus is yellow and black, the males turn blue-black, and if no male in the tank, one of the females will switch sex and assume that role... http://www.cichlid-forum.com/articles/m_auratus.php

 

thanx guys ill look them up

 

I read that somewhere - I will keep an eye on mine, they are now 6months old and all female, so in 4-3months if they do switch sex, it should happen, else they probably dont...

 

It will not happen..... and even the Swordtail implication is a Myth..... It is just a late developing male..... BUT..... they are normally your most beautiful males......

 

It does occur in swordtails, although not often, and is often the case as you say. If I remember correctly, this is because of a different sex determination system in that species.

I can't seem to find anything on African cichlids, but sequential hermaphroditism (female to male change) does seem to occur in some New world cichlids (the Americas). Maybe it can occur here too? More reading is required...

Nerd rant over.

 

Been battling with this one since 1970..... Please someone.... help me out with positive evidence and prove me wrong.... I still say it is not possible......

 

LOL - late developers, that I rate very possible as I breed rhodesian ridgebacks and none of my dam's had their first heat before 14-16months, according to the "dog experts" they are all late developers, supposed to happen between 8-10months in big breeds...

Please let me know if you can find credible evidence of it being possible, from what it seems in the general consensus it is not the case... Proves again not to believe everything my good friend, Google :aetsch:, tells me...
