As Catfish_cz's photos show, the albino, long-fin, and long-fin albino are all mutations of the so-called
Ancistrus sp. 3. I am not saying we will not eventually see mutated
A. triradiatus, just that I have not seen any to date. It also does not make sense from a market point of view. These mutations are already fixed in
A. sp 3, so why spend all the time and energy to fix them in another homely brown
Ancistrus? My guess is that commercial breeders, having fixed these traits, are probably working on doing the same with one of the pretty black and white
Ancistrus sp.
common Ancistrus - hybrid a lot of Ancistrus: Ancistrus dolichopterus x Ancistrus cirrhosus x Ancistrus multispinnis x XY(?) - and I do not know what else ...
This statement I disagree with. We have yet to see any proof of this "old wives tale." My guess is that
A. sp. 3 is one of the early
Ancistrus shipped from Guyana. Asian breeders (and later Eastern European breeders) got their hands on some and set to work with their well-honed mutant
Discus, guppy,
Betta, Angel fish, etc skills and started coming up with fixed mutations.
That said, I have no more proof that they are not hybrids than anyone has that they are. Let me offer the following however,
1) Is it logical that if you start with a population and try to fix a genetic mutation you would crossbreed different spp? No. You would line breed that population generation after generation and cull non-mutants. If you threw in a different sp. to the mix you would throw off the entire breeding program and introduce massive variables and the possibility of infertile offspring which would end your entire experiment. Throw in many different spp., as Catfish_cz suggests, and you would destroy everything you had done.
2) As someone on the Forum pointed out, if they are hybrids, why is there no variation among
A. sp. 3? They all look the same! Albino, long fin, long fin albino, piebald, etc are easily identified as
A sp. 3. Shouldn't we see variation in caudal peduncles, fin patterns, fin ray counts, etc if we are dealing with a crazy mixture of many
Ancistrus spp?
I know that many of these are divided up in the Cat-eLog, but the truth is that they should all probably just be under
A. sp. 3.
