[Killietalk] nigerianus with odd caudal color

That is how my old male looks-yellow on top of caudal and blue on bottom-but his sons look normal. I suspect it is an age thing. You should see his aging mate-she is marked all over with red and gold spangles, quite attractive for a female aphyosemion. Saw her fighting with a retired Chromaphyosemion biv Funge and that female has lots of color too-stripes are gone, replaced by solid pattern and spangles of red and orange. Seems like with my fish it's always the oldest biggest fish that have a color change and it is usually shortly before death. I assumed it was old age. My striatum females do this too-they even get pink spots and yellow in the caudal, with a light green sheen. It doesn't happen to the young small ones, except for a couple batches I raised in plastic storage bins. I quit using those after I saw the fish raised in them were of no particular sex and a very odd pale color. Bettas raised in them never did turn out to be male or female and they don't fight either, just hang out in a school like angelfish. Don't like plastic bins at all anymore... Anyways I am 99% sure that the old male nigerianus did not have the flank pattern extend into the caudal fin until recently and he is very old and large.

Has it ever happened where a body pattern has extended to all unpaired fins?
On the West African site
http://www.killifish.f9.co.uk/Killifish/Killifish%20Website/Index.htm
front page at this time I show a gardneri with an anal fin pattern similar
to the flanks, This fin seems to be the weakest fin regarding cracks in
genes perhaps allied with the pectorals which also seem vulnerable to
change.
Dorsal & caudal fins seem to resist change to this extreme.
Fp.gardneri easily change from yellow to blue phase & sometimes gold in
Nsukka & Misaje populations. An albino of the Akure population has also been
cracked.
The new P82 & German import population photos on this site should rekindle
an interest in these fish.
