Crayfish dont need chiller, our local water temperature is ok.

Crayfish in planted is not very ideal as there's complains of crays pulling out plants to munch.

Crays with shrimps seem ok. I've seen pictures of crays with Cherry shrimps.

Crays with guppies may end up the crays eating guppies.

You can try out with the common ones which cost much less, they're just as fun to watch.

There's 3 types of common crayfish encountered in Singapore's LFS.
1) Redclaw crayfish, Cherax quadricarinatus. From Australia. This gets bigger and are well know to tear up planted tanks.
Identify by the red on the craws. Blue body with red tips on their craw. Quick identification is by the shape of their craws. Cherax got rounder craws and Procambarus got long sharp craws.

2) Red swamp crayfish, Procambarus clarkii. From North America. This is actually the "little lobsters, 小龙虾“ served in restaurants in China/ Chinese restaurants. They're smaller in size compared to the australian red claws. They do get aggressive with one another and bigger ones will eat smaller ones. Provide ample hiding caves if you want to keep a community. The more expensive "ghost" are also P. clarkii line bred for their unique colors. The easiest way to identify them is by bumps/pimples/spikes on their craws. The red-brownish color is the original wild color. There's also blue, orange and white which are still pretty affordable.

3) Blue crayfish, Procambarus alleni. From North America too. They looked very similar to P. clarkii. But, with "camo" pattern on their shell. They also lack the bumps on their craws. Size and aggressiveness should be similar to P. clarkii. Identify by the camo patterns and smooth craws. Wild color is blue to bluish-brown. They were also bred to different color strains. But, I've only saw blue ones on sale locally.

There are also many other more exotic types which are not commonly found in LFS.
