thats hard to say...to many variables.

 

size of tank there in..

quality of food..

quantity of water changes..

 

just to name a few.

my fry from coming out of the cave to selling size...3-4cm takes about 5-6 months

 my bristlenose tanks are 2.5ft

 

 

hope this gives you a idea.

3mths old should be 3cm as a rough guide..... sometimes it takes 2 mths - sometimes 4 mths..... that is commons im talking about.... anything albino is slower....

 

its called food verses water changes... plenty of both....

Do you know roughly how big are the longfins tail compared to the whole body

depends on blood line som,e are longer than others... if you keep them in softer water the fins get longer....

Generally the preferred way to measure a bristlenose is the body length, the fins are ornamental. First time I rocked up somewhere to buy longfins and they didnt mention the 6cm included tail legnth I was a bit miffed, still reluctantly bought them though but it's a few months worth of growth I didn't factor in (was planning on breeding them into my line breeding to boost genetics)

The tail length of a longfin varies largely on the bloodline and how well they were line-bred in the past

common sense should prevail when buying something that has longer fins than normal... one would enquire how you measure your fish and perhaps ask for more detail...and even pics...

a very long time ago.... i think the first 2 i got were from vebas about 7-8 years ago.... had em ever since... well decendants of them anyway... i got albino l/f's off gary when he owned midlant pet/aquarium... and i made calico l/f's from putting calico over common longfin and picking out the 20-25% of calico l/f's and bred them from there...

That's awesome are calico harder to breed than common and how much would 5cm l/f calico go for $$$$

they are all essentially the same fish... just variants... like saying you have black people and they breed for centuries and one day an albino baby is born... it grows up and breeds with another black person and down the track another albino baby is born... then eventually 2 albino people get together and breed and start to form an albino family and then over years the family tree of albino people grows until there are 1000's of them...the same has happened with calicos as albino people... now we have 3 different colour variants of people... .now some people are born with slightly bigger hands and feet... now the tribe leader sees this and thinks if he can get the people with bigger hands and feet to breed together they will get bigger and bigger hands and feet... now this is desirable as they can swim better and faster and catch food better... so over time this tribe has developed long hands/feet much the same as long finned bristlenose....

 

now genetically any of these people can breed together with their colour variant or their developed long hands/feet....

 

hope that makes it easy to understand....

 

now before you ask what about peppermints and orange spots.... 

 

well they are gorillas and orangutangs.... same type of animal as people but cannot interbreed with each other.... 

 

hope you enjoyed the comparrisons :)


5cm calicos - its supply and demand that dictates price.... at the moment i;d say $10-$25 each for fry... quality of the fish may dictate price also....

I can vouch for the water change theory, I did an experiment which I took half my fry from an Albino spawn and put them in a discus tank where I did around 50% once a week and the other half went into different tank, both tanks are 4ft and the discus tank is larger water volume due to the height of the tank. The other tank I put the second half of fry, I did water changes every 2-3 days and they grew atleast 50% larger in the same time period as the ones in the Discus tank over 2 months, at 2 months old the Discus tank fry are around 3cm maybe less, while the other fry in other tank are 4cm easily. So with in my testing I believe that amount of water changes help alot with growth rate.

Has anyone noticed females grow slower, makes you think when trying to purchase the bigger fish for value
