While keeping my flower horns I also kept jelly bean parrots to breed. Jellybeans to me at the time were odd little stumpy looking convicts that were just like parrot fish. There were many rumors for years going around that JB’s( jellybeans) were a hybrid cross between a parrot fish and a white convict cichlids, but from all my research of crossed fish I new there was no possible way. Seeing other post of people luck of crossing species I knew if there was any trace of reddevil in there the outcome out be greater than the size of the parental convict and some devil color should carry over. The only instances I know of for line breeding or crossing where the spawn grow smaller is in parrots and in line breeding for EBJD’s, so I knew there could be no parrot in them. Looking at A jellybean I knew it was just a regular white convict with a genetic skeletal issue. This body shape is genetical recessive and can only be present providing both parents carry this recessive gene. So with this notion I viewed jellybean cons as a miniature parrot fish that could used in the same fashion as the flowerhorn breeders use alter their parrots to shorten the bodies of their flowerhorns. Another plus is both male & female JB’s can reproduce unlike the parrots only the females can breed, the males are mules.
I had an epiphany one day that I you line breed flowerhorns and parrots a few time to get parrot flowerhorns the same theory could occur if you did an experiment of crossing a jellybean( a short bodied convict) to a stripped convict and after a few crosses it may result in a short bodied striped convict. I knew it was a fish you could not buy in the store. I had only kept the jelly beans because they were way more convient to keep. They could be kept in a small space, breed easily, ate less food and a huge plus you could keep many in the same tank.
I had done the first stage of the cross successfully much previously twice and each time this cross occurred and while raising the young of the first stage of the cross I had to move and each time I moved I cleared my fish stock so no fish followed me on the move( huge bummer/ I should have made space). SInce starting the jb x stripe con cross I changed gears the third time and and crossed a jb and a marble convict. In each of my crosses I have always had the jb as the female. Basically following the concept of the parrot where male parrots have the inability to reproduce.
The first cross marble male x jb female the fry were a mix of regular bodied marble and white fish. The second cross is where it got interesting. I took a male from the first cross and breed it back to the mother. Out of the second cross I did get jelly beans but they were all white. The discover i made though was the resulting jellybean curve spine effect was not the same for each jelly bean baby. Individually each fish had its own unique spine curve that was noticeable while the fish were transparent while still young. Each fishes spine went in various directions making them look different in shape. 2 fish actually had extremes where their tails would point in a downward direction. The third cross taking a male from the second batch and crossing it back to the mother gave me a batch of even more jbs and this time getting 2 marble short bodied. Sadly one did not reach it to maturity but the one who did suffered a very minor short bodied effect. Looking at the male I have the spine from the head actually advances upward giving him an almost high back effect. He has a minimal shorting to his body but looking at the anal fin you will notice his anal fin slitty rests on his tail. Recently I have done a 4th cross with this male and have produced again another short bodied marble convict! I have also kept a couple of white jellybeans and will cross them to see if the marble will be recessive in them , possibly white fish could produce marble fry?, we’ll find out. In this stage all the jbs look the same shape where the spine shape from the parents has now locked from the line breeding in one specific fashion. The first picture is my male short body, second image a regular marble con, notice difference in dorsal fin/back shape and length of body in relationship to the tail and anal fin. I also used a picture of a female for the second pic because the females generally are stumpy in physic and thought it would be best to compare. If anyone else out there does this please send me your results plz!!
