Nicaraguensis colouring

Post by ayeo77 » Wed Feb 11, 2015 12:43 pm

Hi all,

my male & female Nics have once again both turned into a bronze colouration after doing so last year and then becoming colourful during breeding. Since then they returned to the dull colouration and the male has developed a line and the female lost hers. This happened in late autumn 13 through to winter 14, and then come Spring 14 they re-coloured up, with the male line disappearing and the female's appearing according to traditional male / female markings. This lasted until the autumn of 14, and then reverted to the their golden / bronze colouring and reversed markings.

They are very healthy fish, and still only about 3 years old.

Is this typical of Nics according to seasons - esp with slight temp fluctuations in water? Or is this seasonal anyway in terms of breeding? Or is there something wrong?

Any advice would be appreciated. thanks. (Sorry don't know why the pics are sideways?)

I never saw this, but mine were all seasons at the same temperature

They are feeding fine, ph has averaged around 7.4-7.5, ammonia 0, nitrates between 30-40, etc and all other fish are well and breeding no problem. These nics are siblings and confirmed male and female. Anyone out there got any expert advice?

Are they the dominant fish in their tank ?

There's a pair of a centrachus spawning consistently in there. The tank is six foot by two foot. There is also a 4" rostratum in there, plus astyanax aenues and livebearers

How old or big are these two? When I bought my nic she was brown, but once she got older she colored up nicely. She did turn brown to bronze to orange. Another possibility is the other breeding pair you have. Are they stressing the nic pair out? Stress can put fish through color changes.

They are around 3 years and 6 months old. They are 6 inches (male) and 4.5 inches long (female). So they are still not fully grown. There is a full grown male A Centrarchus and female AC spawning in the tank and a sub adult 4.5" A Rostratus. They all square up from time to time but nothing ever serious.

Also they are siblings from the same parents - is that a factor? Would water temp be a factor?

My male nic keeps more or less the same coloration year round, but the female turns into a dull light bronze color when she is bullied. I had the best, consistent colors in my nics when two pairs were together in one tank.
