Sunbird73 Posted October 17, 2010 Report Share Posted October 17, 2010 They had labelled the tank cockatoos - some confusion as they had come in from the wholesaler as cockatoo double reds apparently, so maybe thats why the price? (are now labelled agassizi ).. They said that it wouldn't alter the price - maybe they paid a cheaper price for them because they came in as something different?

danval Posted October 20, 2010 Author Report Share Posted October 20, 2010 LFS has just got some of these in and all males priced at $49. Three in the tank and 2 are very small, 1 is smallish but not a bad looker!. Why so many males around?. Maybe like me and bred them at higher temps :-?

phoenix44 Posted October 20, 2010 Report Share Posted October 20, 2010 I bred them at 24 C and got 9m and 2f. Quote Link to comment Share on other sites More sharing options...
danval Posted October 20, 2010 Author Report Share Posted October 20, 2010 24 c lower end of their range and still only small amount of females?. I have heard that PH has a part to play when determining sex also.... but then in other readings off the net I have seen 50/50 ratios in 26 c water :-?

ryanjury Posted October 20, 2010 Report Share Posted October 20, 2010 Yeah 50/50 at 26 is what I usually work on too.. However that might not apply to all apistos so hard to know Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 20, 2010 Report Share Posted October 20, 2010 That's why I asked you to separate the fry a few posts ago. Might be a bit too late now. Quote Link to comment Share on other sites More sharing options...
danval Posted October 20, 2010 Author Report Share Posted October 20, 2010 Seperate the fry for what reason? Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 20, 2010 Report Share Posted October 20, 2010 because I could have sworn one of my females became a male. Maybe hormones have a role to play in sex determination... Quote Link to comment Share on other sites More sharing options...
danval Posted October 20, 2010 Author Report Share Posted October 20, 2010 From my readings the sex is determined very early on.... Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 20, 2010 Report Share Posted October 20, 2010 yes, that's what ive read too, but then again we have both read about the temp thing too and that doesn't work either. Quote Link to comment Share on other sites More sharing options...
danval Posted October 20, 2010 Author Report Share Posted October 20, 2010 Too true I could never have seperated them even if I had wanted as I didn't know and still don't know which are males and which are females. I think they are all males! Quote Link to comment Share on other sites More sharing options...
ryanjury Posted October 20, 2010 Report Share Posted October 20, 2010 Time will tell, apistos are hard to sex at times just let them grow out a bit and you will see what you have Quote Link to comment Share on other sites More sharing options...
antwan Posted October 20, 2010 Report Share Posted October 20, 2010 I agree with Ryan, time is best with these fish as they can be very tricky. I bred my tri's at around 30C (summer) and all turned out male. I could have sworn I had a few females and even sold them to friends in pairs only to find out they were less dominant males Quote Link to comment Share on other sites More sharing options...
danval Posted October 20, 2010 Author Report Share Posted October 20, 2010 Thanks guys. Most of my fry look to be definite males but there are a few which seem to be a lot lighter in colour and with less iridescent markings, especially around the gill plate. Here's hoping!

Bilbo Posted October 20, 2010 Report Share Posted October 20, 2010 I have had agassizi for many years and have never heard of the gill plate thing. If true then that's information that would have come in really handy a number of times. The sex ratio argument is still not properly understood but temperature is a supposed to be a major factor. Other ideas like TDS and pH are supposed to be important too. My last spawn of agassizi was mostly females (Didn't get a single male to maturity) and I think it was about 26 - 27c but it would have been when I started using filtered rain water and peat so I guess the water would have been pretty soft and full of tannins with a pH in the high 5's to low 6's.

danval Posted October 25, 2010 Author Report Share Posted October 25, 2010 More pics.. Most of them poor but you get the idea.. Some fish are alot darker with more irridescence but not necessarily any more agressive. Could these be males? Some are quite yellow with the distinctive black line (maybe females?). And there is one that is alot paler than all the rest with a faded black vertical line.... Most are starting to develop redish tails Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 25, 2010 Report Share Posted October 25, 2010 They look quite cool. Mine are about 3 and a bit months old now (maybe 4?) and I have the female guarding a batch of eggs this morning! :lol: Quote Link to comment Share on other sites More sharing options...
danval Posted October 25, 2010 Author Report Share Posted October 25, 2010 Wow that is awesome to have her spawning at such a young age, but then you did get them to grow very fast!. Are you going to lower the temp and try and get more females this time? Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted October 25, 2010 Report Share Posted October 25, 2010 well they were bred at the lower end of the spectrum last time, and I got 9m 2f so this time ill try the separation method I mentioned before. That is provided this female makes a good mother. Quote Link to comment Share on other sites More sharing options...

blueyes Posted October 25, 2010 Report Share Posted October 25, 2010 I might do at some stage, for now I am just concentrating on getting my new tank set up Quote Link to comment Share on other sites More sharing options...
danval Posted November 22, 2010 Author Report Share Posted November 22, 2010 I have removed 4 definite males from this lot and have a video of the other 30 odd... What do you guys think.. Males or Females? Hope you like the background music :lol: Quote Link to comment Share on other sites More sharing options...
ryanjury Posted November 22, 2010 Report Share Posted November 22, 2010 lol it is very hard to tell from that low res video but they all still look very uncoloured.. I would give them more time.. Quote Link to comment Share on other sites More sharing options...
