These came in 6-7 weeks ago as Copella 'red line' i think they are C.nattereri but the genus is so confusing with little in the way of published material that its very difficult to get a 100% accurate ID on these fish!
Yesterday i set them up in a breeding tank and today while i was out they have spawned a small clutch of eggs on a artificial plant.. Im really pleased to get a early spawn but a bit disapointed to miss the action.

Hi Matt, these are Peruvian, direct from Iquitos to Manchester airport where i collected them! These fish have been reclassified many times, current thought is that this species with a single red stripe is C.nattereri and the fish with multiple broken lines is C.meinkeni(often refered to as C.nattereri).. Toms done more research than me and i get most of my Id's here.. http://apisto.sites.no/slekt.a.....gruppeID=5
Finding concrete evidence on ID'ing these fish is like p***ing in the wind... Very difficult with the chance of embarresment /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
Im currently in touch with both Ralf Britz and a Brasilian scientist who studies Copella, im currently preserving a 60 day series of fry from C.arnoldi for use in a scientific paper, i may well call in a favour and see if i can pin each species down with a definate ID.. Ill add it to my list of 101 things to do!!
Ive had arnoldi in for a while and have had two spawns but both times the eggs have fungussed... any thoughts?
Hi Colin, good to speak again, not seen you around for ages. Hows things?
Luckily for me my arnoldi spawns are almost 100% fertile 99% of the time.. Its obviously a fertility problem, how old are the fish? what are they spawning on? i used to get poorer results when mine jumped to the cover glass, the gravity was a stronger pull and it seemed they always spent a second or so less when laying/fertilising the eggs than they do with my current method.
I now drop the water level a good 6 inches so stop them spawning on the coverglass, then utilise plastic/silk plants with removeable leaves, once i have a spawn(most days!) i remove the eggs along with the leaf and place them imersed in a 2 litre container where they hatch and live for the first 10 days while on paramecium.. Once on baby brineshrimp they are moved to a larger 5 litre container for a further week or so and then into a 20 litre filtered glass tank and eventually larger again as they outgrow it..A lot of work but a lot of fun and learning /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> i love these fish...
Doing fine here - just keeping really busy! /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
Yeah, they are spawning on the cover - actually a black moulded plastic lid - rather than on a leaf. I have not set the fish up to spawn, just a holding tank but will try and perhaps use a cheese plant (Monstera) leaf this week to see if it helps? They have about a 3" jump to the lid just now...
So, to clarify, when you move the leaf you place the eggs underwater rather than leaving them above the water?

Well, that seems to have worked a lot better - still some white eggs but the vast majority look well... /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />
I used a Cheese Plant leaf (Monstera delicossa) about 8cm above the water level... too high?
