So many variants! interesting :D

Yup, helps to lower the pH and buffers the water.

Bro Dave u got a very nice pair of ghost!!!:)

The ghost is it expensive? I saw some white and red coloured cray at Y618 and it is priced 3 digits.

most crayfish are good with water pH in the neutral range. 7+/-

thanks. P. clarkii "ghosts" are vert easy to like for their colors and active lifestyle.
yes, for now, its about 2 to 3 blue notes, depending on size.
but, many are breeding them. so price should be coming down.
i am also expecting more color variants for P. clarkii in the near future. there's red, orange, blue, white, baby blue, ghost, clear ghost orange, clear ghost blue now.
with more breeding of different color combinations, more color morphs should be popping up soon.

Oh so these ghost are basically hybrids, are there albino crays as well?

no, not hybrids.

They are Procambarus clarkii.

They are actually the very popular 小龙虾 (little lobsters) served on dinning tables in China

Just line bred for their attractive colors.

In the original form, they are dark red in color.

Then hobbyists line bred them into the different colors.

Just like many domesticated fishes & animals in the hobby, eg, guppies, betta, mollies, shrimps, etc...

Oh like the cherry shrimps can breed out blue, brown and black. So far I have not seen any albino shrimps yet.
