The xanthic carrier jags spawned today. Just got the confirmation text. Ian tells me that it can take over two weeks before the fry become free swimming, so I won't get too excited just yet. The parents took three days just to clean the spawning site to their satisfaction!
I have decided that the xanthic gene should be labelled 'Y' (for yellow colouration). With this in mind, the Punnet square that predicts how the offspring will turn out should look like this:
Y y
--------------
Y YY Yy
y Yy yy
So, 25% normal, 50% xanthic carriers (which are apparently phenotypically distinct from normals), and 25% xanthic.
This is what Ian seems to have got from the last spawn with the same female, but only time will tell whether or not the fry he believes to be xanthic really are. The same goes for whether or not the carriers will be distinct from the normals. I must remember to ask.
For now I have to start worrying about the best way to feed the fry when they start swimming.

Gold farming!
24th - 26th June. Bank Holiday Weekend!
Got the six foot tank moved onto the floor in the fishroom and set it up to hold a pair of xanthic carrier jags. My mate Ian is lending me his female to look after while he's away in Africa. As a result, phase one of our xanthic jag breeding program has started. The two fish have been busily cleaning a spawning site all weekend, so I have high hopes for a large spawn in the near future, 25% of which will be xanthic, just like their grandfather:
The two four foot tanks in the fishroom still both have high nitrite levels, which is bad news, but hopefully I can doo some big water chages next weekend. Hopefully the sponge filters will kick in soon!
BULLETS:
- Female Honduran Red Point improving after treatment with Sterazin. Trying to fatten her up with eggs so I can reintroduce her to the male. I recently found out that they are probably 'Rio Danli' strain.
- Moved JD x EBJD pair into their own tank.
- Shifted the two spare Bangui jewels to Simon in exchange for five of his home-bred Blockheads (I really hope I got at least one female in there!). This means I now have 7 Blockheads in one 24" tank in the fishroom.
- Put a pair of cutteri in the 30" office tank. Used the male withe the most red in his fins. All my female Cutteri are showing their egg-laying tubes now.
- Festae have started to pair.
- I have HRP x Convict fry and Bangui fry this weekend.
