Identifying females

["Nuno Prazeres" <nprazeres@vodafone.pt>]

Dear friends,

I have been trying to spawn a trio of agassizii but after 9 different spawns never saw any wigglers - the eggs just start disapearing on day 3 however they dont seem to catch any fungus - they never become whitish.

Water parameters look more or less ok - pH 6,4, DH 2 Temp 24 (I know :-) it could be a little warmer). I feed them only live food - daphnia, grindal worms and grey mosquito larvae, the latter representing almost 80% of the diet which might explain why they spawn with only 10 days intervals. Agressive water changing is also used (10 to 30% between 3 and 5 times per week).

I am starting to get suspicious about the females. When they spawn they dont become as yellow as some other aga females I know, the eggs are just slightly redish which differ from the regular aga ones I saw before. One intriging detail is the fact that they show a double spot when in spawning coloration. I never heard anything about a double spot in aga females. However, this are not wild specimens for sure so selective breeding might explain the fact.

Hopefully I will get some pics, but for now I would just like to ask for your help concerning this double spot issue. Do aga females show double spots? If not which species do?

Thanks in advance and Merry Xtmas
