CPO Temp and Questions

I'm getting some conflicting information on what temperatures to keep CPOs. What temperatures have you kept yours in and allowed them to breed?

for a second, it peaked my interests to see that someone actually cared about the body temperature of a dwarf cray. LOL

I kept mine consistently at 75. lower temps inhibit breeding and their metabolism slows down quite a bit. I dont recommend keeping them in temps beyond 78...

I was more concerned if I'll need to get a heater for a Fluval Spec V that I'm setting up for my CPOs

You don't need a heater, i never used one and they got down to lower 60's in the winter.

Mine breed pretty well in the summer (75-80), and have stopped breeding after temp dropped under 72. They are still pretty active and always try to catch the orange shrimps in the same tank. Oh, the fact the two big female managed to kill 2 male a month ago didn't help breeding either lol.

"two big female managed to kill 2 male a month ago didn't help breeding either lol."


I was planning on getting a pair but because of reading this from so many people, opted not too.

Hey, they are fun to watch and well worth the effort. If I'm serious about breeding them I would separate the berried female out in a breeder box. Most of my baby CPO won't grow bigger than 1/2" before getting caught by the big females... The orange neos in the same tank fair better because they are much smarter than baby CPOs ;-)

I do not want to worry about the female killing the male and it does seem that this happens .

I might look at the orange Procambarus milleri which I have never seen for sale but read about them and heard not illegal to sell or buy.

Plenty of Berrried Females at 64 Degrees . Gestation and growth rates may be slower at lower temperatures though . But the egg clutches seem really healthy . In nature most crays get the sperm packet in the fall and the eggs hatch in the cold water of spring

It's listed as an endangered species on the IUCN Red List. Perhaps that's a reason you've not seen it for sale.

My thinking has been invert-ed!

Thank you for the responses! I currently have 4 of the CPOs in my Fluval Spec V with Shells and PVCs as hiding spots. The temperature is around 70 degrees (room temp) and they seem to be doing well, a little sluggish though, so I may end up investing in a real heater later on.

Got a few more questions, I have about 6 seashells in the tank and would like to add more to increase the hiding spaces for babies in the future. Would I have too many if I added maybe 7-8 more smaller shells?

Too many?
Like, will it look bad with more? Or are you afraid of them dissolving in there?

I wouldn't be too worried, cpo are fine with many different parameters.
