In 2015, there was a a report on newly described crayfish. According to the report, the wild population already in decline due to aquarium.

I wonder if it has been imported into Singapore?

Research Article published on ZooKeys by Christian Lukhaup

"Cherax (Astaconephrops) pulcher, a new species of freshwater crayfish (Crustacea, Decapoda, Parastacidae) from the Kepala Burung (Vogelkop) Peninsula, Irian Jaya (West Papua), Indonesia"

Dropped by Y618 yesterday after work. My first trip after hearing abt the shop from many bros on AF over years.

Saw dwarf crayfish (labeled as dwarf lobster) about 1 to 2cm each on display on the shelf beside counter. Tempted to get it. But decided to do some research, reading up on AF first.

After reading old threads, it seems the price has dropped over the years. Used to be much expensive. (Now at $6 each for those wondering). Read that it's friendly to fishes, shrimps and wouldn't uproot the plants.

Any bros still keeping dwarf crayfish (or breeders with excess to let go?

) Care to share experience? Need chiller? Some bros mentioned keeping them in chilled tank 25 to 26C.

I think they are referred to as CPO here.

Yes, CPO... there are the orange and light brown versions (both are common). I could consider these since they are less aggressive towards plants and shrimps. Only concern is feeding,
- If they can get ample food since they are slower than shrimps.
- What about 'starving' period (when i go on vacation)?

I had CPOs before and they breed. Made a mistake of keeping them in breeding container, and ended up losing them one after another.

Crayfishs need minerals to grow new shell for molting.
If they dont get enough minerals, they'll have difficulty molting and will die.

Some keepers are dosing minerals for their crayfish. I've seen someone used the minerals for rift lake cichlids, but dosage was lower than those for rift lake cichlids.

I also read somewhere that there's a requirement for GH for crayfish. but cant find the required numbers.

Looks like it is not a easy keeping.

Anyone can provide a Keeping ABC Guide on this?
