I went yesterday to a LFS and they had some blue dolphin moorii in and i went ahead and bought 3 from them, I noticed the ones they had in which was about 10 or so most of them had some sort of this reddish/brown colour on the anal fins of the dolphin moorii. The guy there said it might be the light and so i took his word and when i brought the 3 back into my tank 2 of them look more normal looking now they had a hint of red which is gone now and the 3rd one still has this colour on it in my tank. Is this normal? I have never seen this before and the LFS apparently is one of the best shops around in my area they take extremely good care of their fish their tanks are really clean all their fish look really healthy so i had no reason to doubt them. First 2 pictures is the dolphin with the strange coloured fin next 2 are the other 2 i bought with it from the same tank.
i have a very large group of 14 of around the same size as these about 1-3 inches each dolphins at the moment 7 from one seller and 7 from another so 2 sources and now a third source these ones which makes it 17. The other 2 groups none have this red colour to them I'm wanting to breed them and will eventually thin my group out keep the best looking 2-3 males and remove extra males and keep whatever females i got.
on a side note i read around for sexing dophins at this size can be done? I wanted more females so i tried to pick them out based on the anal fins did i pick the correct sexes? the one male looking one has a very long pointed anal fin past the tail fin and the other 2 are blunt short and not past the tail fin? Also it is usually better to have different sources so that you don't end up only breeding sibling fish?
Any help would be appreciated thanks.
