Ancistrus ranunculus growth rate

The more common Ancistrus species grow fairly fast, at least compared to Peckoltia/Panaqolus/Hypancistrus etc. Is this also the case with A.ranunculus, or is it more of a slow grower? Have any of you kept other Ancistrus species from the same area as A.ranunculus and been able to compare growth rates?

If L255 is truly A. ranunculus, I have not witnessed ANY growth from these fish in nearly a year and a half. If that means they're already full adult, than the guesses of this fish reaching upwards of 8" is incorrect. None of my 8 are even a full 6".

That really doesn't answer your question though, does it?

Well given the obvious similarity between A.ranunculus and L-255, it does actually give me a useful answer, because it adds to my suspicion that these Ancistrus are in fact slow growers. I had a pair of L-255 in the store where I work and they measured approx 5", and I have never seen bigger specimens. The biggest specimens of A.ranunculus I have seen were approx 6". There is certainly something special about these 2(?) species, with the seemingly slow growth an the difficulties we experience with just keeping them alive and well for a longer period of time!

Haakon: Can you tell me which store you're working in, 'cause I'm looking for some L-255, and have only seen them once in Norway.

Slow, slow, slow topping out around 6". 84-86F really perks up their appetites, and although it may not be obvious, might help the growth rate. Mine are over five years old and in that time have grown from two inches to six, where they have been for about a year.

Thanx for the info, again it confirms my beliefs

Have you bred them? Any idea what size they need to be to spawn? And you wouldn't happen to have any pics to share?
