This isn't a photo i've taken but I saw these in my local maidenhead aquatics at the weekend and have been hunting for a description since! Tiny fish with brightly coloured males and silver females. They were listed as 'chilli rasbora' I believe but that common name seems to cover loads of different fish.
They're endlers. Livebearers very closely related to the guppy (some say they are guppies). They're quite new but there's lots of information around about them. Do a google search for 'endlers' and you'll be reading for hours!
They are definately endlers and both of them in the pic are males. They are great fun to watch. I have been breeding them for awhile. The are very easy to breed and they are not aggresive. How many have you got? I started off with about 20 babies and now i have about 60. That is after about 6 months, if that.
Ahh, that label was over the adjoining tank, must have been moved. None yet as I had just purchased 4 honey gourami but I think they may well be my next addition. Any experience on keeping them with other fish? I have 6 tetras, 4 gourami and 6 corys atm.
Should be fine. The males are quite small though (as you've seen) so don't keep with large fish (angels etc). As with most livebearers keep more females than males as the males are quite persistent and wear the females out.
Out of interest, how much are they being sold for?
They will be fine with all the fish that you have listed. Ours are with a couple of banded plecs, 4 corys, 1 clown loach and a red finned loach, red tailed black shark and everyone gets on well. When we bought ours they were 50p each but they were babies at the time. I think they are now about £2 or less, not sure. The breeding thing is easy you just let them get on with it. They will have babies 3-4 wks.
