I know its nothing particulary new but these fish facinate me, ive been breeding them seriously for around 12 months and currently have well over 1000 in the fishroom at all ages and sizes. They are prolific spawners and its not unusual to get a clutch of eggs everyday, certainly every two days.

Most of the time i let them get on with it and just observe them while im busy with other jobs, last week i got the camera out and got a few pics to support the article im in the middle of writing. I thought id share them on here.

Good pics! I am thinking about getting some of these myself.

I am working with Pyrrhulina zigzag once in a while but have trouble raising the fry for the fist few weeks. How do you keep and feed your youngsters? I think I could use some tricks...

Hi Kim, i would definately recomend them, you would not regret owning them..

I remove the eggs and hatch them in small shallow plastic containers holding around 2 litres of water, in these plastic tubs the fry are kept for upto 4 weeks and fed infusoria for the first 2 weeks and then small amounts of brineshrimp and microworm, obviously once on the more meaty foods with such a small volume of water i have to perform daily waterchanges, usually 100% of the water is changed for prewarmed fresh water, even with 5-6 tubs on the go its only a 10-20 minute job..

Heres the location of the tubs and foods in my fishroom.

Thanks for the tips! And nice setup /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Although I have tried to remove eggs from the zigzags without much luck (they fungused) I can move the fry when they are free swimming and try to feed them in the small tubs.

Copella arnoldi is definitely one of my all time favourites..before my " betta-days" - I used to breed them.

I used to start the very small fry on paramaecium...Someday I might very well go back end enjoy

Do breeding males of C. arnoldi always have a dark horizontal bar extending from behind the gills as per Ste's fish above?

Lovely-looking fish Graham, ok to add that one to the profile?

It appears to be what Zarske (2011) considers to be the 'real' C. arnoldi but would appreciate any additional input.

Brilliant, thanks. Will add it now.

Have been translating some papers by Zarske and Géry (2006) and Zarske (2011), and it appears this fish is now considered to be C. callolepis, similar to C. meinkeni and referred to as cf. meinkeni in some earlier works.
